Abstract

An object of the present invention is to improve assembling workability of the flow passage block and the sealability between the manifold solenoid valve and the flow passage block. A flow passage block 61 is mounted on a manifold solenoid valve having valve bases 12 on which solenoid valves 11 are respectively mounted, a block mounting face 60 is formed by the valve bases 12 , an output joint 36 protrudes from each valve base, a joint seal member 71 is detachably mounted on the output joint 36 , with the flow passage block 61 being mounted on the block mounting face 60 , the joint seal member 71 seals between an outer peripheral surface of an output joint 36 and an inner peripheral surface of an connecting hole 64 which communicates with an air passage of the flow passage block 61.

First claim

What is claimed is:

1. A manifold solenoid valve, comprising:
valve bases on which solenoid valves are respectively mounted;
output joints which are provided so as to protrude from the respective valve bases, the output joints communicating with output ports of the solenoid valves, and each output joint having an annular engaging protruding part projecting radially from an outer peripheral surface;
joint seal members mounted on the output joints for outputting air, each joint seal member having an inner peripheral surface and an outer peripheral surface, the inner peripheral surfaces of the joint seal members engaging the outer peripheral surfaces of the output joints;
wherein an annular recess part is provided on the inner peripheral surface of each joint seal member,
the annular engaging protruding part of each output joint projecting radially is fitted into the annular recess part of the joint seal member, and
at least one annular protruding seal part is provided on the outer peripheral surface of the joint seal members, and the one annular protruding seal part is disposed so as to correspond to the annular engaging protruding part of the output joints,
wherein the annular engaging protruding part projecting radially from the peripheral surface of each output joint has:
a cylindrical outer surface with a proximal end and a distal end;
a tapered surface extending from the distal end of the cylindrical outer surface toward a distal end of the output joint; and
a radially directed surface extending radially inwardly from the proximal end of the cylindrical outer surface.

2. The manifold solenoid valve according to claim 1 , wherein a block mounting face, on which a flow passage block is mounted, is formed by the valve bases abutting on each other.

3. The manifold solenoid valve, according to claim 2 , wherein
the at least one annular protruding seal part comprises first and second annular protruding seal parts integrally provided on the outer peripheral surface of the joint seal member, with the first annular protruding part corresponding to the annular engaging protruding part of the output joint; and
the first and second annular protruding seal parts of the joint seal member are brought into contact with an inner peripheral surface of a connecting hole of the flow passage block.

4. The manifold solenoid valve according to claim 3 , wherein
the second annular protruding part of the joint seal member is located between the first annular protruding part of the joint seal member and the valve base.

5. The manifold solenoid valve according to claim 3 , wherein
a distal end of the joint seal member is disposed between an end face of the output joint and a bottom face of the connecting hole of the flow passage block.

6. The manifold solenoid valve according to claim 2 , comprising end blocks which are mounted on end faces of a valve base assembly formed by abutting the valve bases, each end block is provided with an extension face which is continuous to the block mounting face, wherein
at least one of an air supply joint for communicating with an air supply port of the solenoid valve and an exhaust joint for communicating with an exhaust port of the solenoid valve are provided on at least one of the end block so as to protrude from the extension face,
a joint seal member for supplying and exhausting air is detachably mounted on at least one of the air supply joint and the exhaust joint, and
the joint seal member for supplying and exhausting air has a recess part on an inner peripheral surface thereof, an annular engaging protruding part of an outer peripheral surface of at least one of the air supply joint and the exhaust joint is fitted into the recess part; and the joint seal member for supplying and exhausting air further has an annular protruding seal part on an outer peripheral surface thereof.

7. The manifold solenoid valve according to claim 6 further comprising:
a first end block which is mounted on one end face of a valve base assembly formed by abutting the valve bases, and which is provided with a first extension face which is continuous to the block mounting face,
a second end block which is mounted on the other end face of the valve base assembly formed by abutting the valve bases, and which is provided with a second extension face which is continuous to the block mounting face,

wherein an air supply joint for communicating with an air supply port of the solenoid valve is provided so as to protrude from the first extension face of one of the first and second end blocks,
an exhaust joint for communicating with an exhaust port of the solenoid valve is provided so as to protrude from the second extension face of the other of the first and second end blocks, and
the joint seal members for supplying and exhausting air are detachably mounted on the air supply joint and the exhaust joint, respectively.
