Abstract

A compressed air system contains a compressed air reservoir, a compressed air line system and a drive system connected on an inlet side to the compressed air reservoir by way of the compressed air line system. The drive system has a drive and a drive controller, the drive system has a valve provided so as to pneumatically separate the drive controller from the drive.

First claim

1 - 13 . (canceled)

14 . A compressed air system, comprising:
a compressed air reservoir; a compressed air line system; and a drive system having an inlet side connected to said compressed air reservoir by way of said compressed air line system, said drive system having a drive and a drive controller, said drive system having a valve provided so as to pneumatically separate said drive controller from said drive.

15 . The compressed air system according to claim 14 , wherein said drive controller is a control unit having a sensor for measuring a control variable of said drive, and also a feedback connected to an inlet of said control unit.

16 . The compressed air system according to claim 14 , wherein said drive is a current collector drive of a rail-borne vehicle, said drive being provided to raise and/or lower a current collector of the rail-borne vehicle in dependence upon an inlet pressure of said drive, said inlet pressure being controlled by said drive controller.

17 . The compressed air system according to claim 14 , further comprising a bypass connected between said compressed air reservoir and said drive and is provided to bridge said drive controller when in a state in which said drive controller is pneumatically separated from said drive.

18 . The compressed air system according to claim 17 , wherein said bypass has an auxiliary controller for controlling an inlet pressure of said drive.

19 . The compressed air system according to claim 18 , wherein said auxiliary controller is a pressure reducer.

20 . The compressed air system according to claim 17 , wherein:
said valve of said drive system is a shuttle valve having two inlets and one outlet; and said bypass having a directional control valve with one inlet and two outlets, said bypass having an outlet side connected to said drive by way of said shuttle valve and an inlet side connected to said compressed air reservoir by way of said directional control valve.

21 . The compressed air system according to claim 14 , further comprising a further compressed air reservoir connected to said drive by way of said compressed air line system so as to supply said drive with compressed air, when in a state in which said drive controller is pneumatically separated from said drive.

22 . The compressed air system according to claim 21 , wherein said further compressed air reservoir is connected to said drive by way of said compressed air line system on an outlet side of said drive controller.

23 . The compressed air system according to claim 21 , wherein said further compressed air reservoir and said drive are connected in a parallel connection to said drive controller by way of said compressed air line system.

24 . The compressed air system according to claim 21 , wherein said compressed air line system contains a further valve disposed between said further compressed air reservoir and said drive, said further valve pneumatically separating said further compressed air reservoir from said drive.

25 . The compressed air system according to claim 14 , further comprising a pressure measuring device connected to said drive by way of said compressed air line system, said pressure measuring device is disposed directly upstream of an inlet of said drive.

26 . The compressed air system according to claim 21 , wherein said further compressed air reservoir is connected to said drive by way of said compressed air line system on an outlet side of said valve of said drive system.

27 . A method for parking a rail-borne vehicle in which the rail-borne vehicle is braked to a standstill in a case of a current collector being connected to a line that conducts current, which comprises the step of:
separating pneumatically a current collector drive from a drive controller by means of a valve and the current collector of the rail-borne vehicle furthermore remains in contact with the line that is conducting current.
