Abstract

Device for supplying pressurized fluid, including a first valve accommodating an internal fluid circuit, the device having a second valve having an internal circuit, the second valve forming a separate physical entity from the first valve, the first valve and the second valve having respective coupling members that form a male/female quick-connection system for removably connecting the second valve to the first valve, the internal circuits including a set of control valves for allowing or preventing the flow of the fluid towards an outlet of the device when the second valve is coupled to the first valve via the quick-connection system.

First claim

What is claimed is:

1. A device for supplying pressurized fluid, comprising:
a first valve accommodating an internal fluid circuit,
a second valve comprising an internal circuit,
the second valve forming a separate physical entity from the first valve,
the first valve and the second valve comprising respective coupling members that form a male/female quick-connection system for removably connecting the second valve to the first valve,
the internal circuits comprising a set of control valves for allowing or preventing the flow of the fluid towards an outlet of the device when the second valve is coupled to the first valve via the quick-connection system,

the device comprising:
at least one manually actuable movable control member for controlling the set of control valves,
the control member being movable between a first, rest position, in which the flow of fluid towards the outlet is prevented, and a second, active position, in which the flow of fluid towards the outlet is allowed,

the quick-connection system comprising:
a connection piece for connecting the second valve to the first valve,
the connection piece being movable between a first position, in which the quick connection between the second valve and the first valve has not been established, and a second position, in which the quick connection between the second valve and the first valve has been established,

wherein,
in the first position, the connection piece blocks the control member in the first, rest position so as to prevent movement towards the second, active position, and in that,
in the second position, the connection piece does not block the control member in the first, rest position so as to allow movement towards the second, active position, and in that,
in the second, active position, the control member blocks the connection piece in the second position, so as to prevent the second valve and the first valve from being separated, and in that,
in the first, rest position, the control member does not block the connection piece in the second position, so as to allow movement towards the first position and thus allow the second valve and the first valve to be separated,

wherein the blocking of the control member by the connection piece is mechanical blocking brought about by an intermediate piece of the device that cooperates on one side with a portion of the control member and on the other side with the connection piece, so as to form or not to form a mechanical end stop for the control member depending on the position of the connection piece, and
wherein the intermediate piece comprises a movable pin that is acted on by a return member.

2. A device for supplying pressurized fluid, comprising:
a first valve accommodating an internal fluid circuit,
a second valve comprising an internal circuit,
the second valve forming a separate physical entity from the first valve,
the first valve and the second valve comprising respective coupling members that form a male/female quick-connection system for removably connecting the second valve to the first valve,
the internal circuits comprising a set of control valves for allowing or preventing the flow of the fluid towards an outlet of the device when the second valve is coupled to the first valve via the quick-connection system,

the device comprising:
at least one manually actuable movable control member for controlling the set of control valves,
the control member being movable between a first, rest position, in which the flow of fluid towards the outlet is prevented, and a second, active position, in which the flow of fluid towards the outlet is allowed,

the quick-connection system comprising:
a connection piece for connecting the second valve to the first valve,
the connection piece being movable between a first position, in which the quick connection between the second valve and the first valve has not been established, and a second position, in which the quick connection between the second valve and the first valve has been established,

wherein,
in the first position, the connection piece blocks the control member in the first, rest position so as to prevent movement towards the second, active position, and in that,
in the second position, the connection piece does not block the control member in the first, rest position so as to allow movement towards the second, active position, and in that,
in the second, active position, the control member blocks the connection piece in the second position, so as to prevent the second valve and the first valve from being separated, and in that,
in the first, rest position, the control member does not block the connection piece in the second position, so as to allow movement towards the first position and thus allow the second valve and the first valve to be separated,

wherein the blocking of the control member by the connection piece is mechanical blocking brought about by an intermediate piece of the device that cooperates on one side with a portion of the control member and on the other side with the connection piece, so as to form or not to form a mechanical end stop for the control member depending on the position of the connection piece, and
wherein the intermediate piece comprises a stem that is secured to the control member and cooperates or does not cooperate by abutment with the connection piece depending on the position of the latter.

3. A device for supplying pressurized fluid, comprising:
a first valve accommodating an internal fluid circuit,
a second valve comprising an internal circuit,
the second valve forming a separate physical entity from the first valve,
the first valve and the second valve comprising respective coupling members that form a male/female quick-connection system for removably connecting the second valve to the first valve,
the internal circuits comprising a set of control valves for allowing or preventing the flow of the fluid towards an outlet of the device when the second valve is coupled to the first valve via the quick-connection system,

the device comprising:
at least one manually actuable movable control member for controlling the set of control valves,
the control member being movable between a first, rest position, in which the flow of fluid towards the outlet is prevented, and a second, active position, in which the flow of fluid towards the outlet is allowed,

the quick-connection system comprising:
a connection piece for connecting the second valve to the first valve,
the connection piece being movable between a first position, in which the quick connection between the second valve and the first valve has not been established, and a second position, in which the quick connection between the second valve and the first valve has been established,

wherein,
in the first position, the connection piece blocks the control member in the first, rest position so as to prevent movement towards the second, active position, and in that,
in the second position, the connection piece does not block the control member in the first, rest position so as to allow movement towards the second, active position, and in that,
in the second, active position, the control member blocks the connection piece in the second position, so as to prevent the second valve and the first valve from being separated, and in that,
in the first, rest position, the control member does not block the connection piece in the second position, so as to allow movement towards the first position and thus allow the second valve and the first valve to be separated,

wherein the blocking of the control member by the connection piece is mechanical blocking brought about by an intermediate piece of the device that cooperates on one side with a portion of the control member and on the other side with the c
