摘要： An actuator responsive to fluid signals to retract and extend a piston. The actuator includes a cylinder and a pressure piston carried inside the cylinder. Also included is a shaft, and a rod connected to the pressure piston. The actuator further includes a first port for receiving a fluid pressure to move the pressure piston to a first position. The actuator also has a locking mechanism. The locking mechanism has a first and second surface, and both surfaces are movable in response to the fluid pressure at the first port. The surfaces lock the pressure piston in a first position upon removal of the fluid pressure at the first port.

摘要： In a rail vehicle hand brake having a release activated by a pneumatic cylinder, the present control system includes a manual valve having an output connected to a source of pressure at an input when manually activated. A volume is to be charged by the source of pressure. A choke connects the volume to exhaust. The volume and the choke prolong the time the source of pressure is connected to the pneumatic cylinder after the manual valve is activated.

摘要： The present invention is a parking brake for a rail vehicle having a brake cylinder and a piston in the brake cylinder responsive to forces to apply and release the brakes on the vehicle. The parking brake further includes at least one off-center connecting rod extending though an opening in the brake cylinder and connected to the piston through that opening. The parking brake also includes a force multiplier supported by the brake cylinder and connected to the at least one off-center connecting rod. Further included is an actuator connected to the force multiplier for driving the force multiplier to provide the force to move the at least one rod and the piston to move the brakes to an apply position.
