| Number | Title | Issue Date |
| 6269916 | Brake cylinder using dual piston assemblies A brake cylinder for use in a railway vehicle braking system is provided. The brake cylinder comprises a cylindrical casing engageable with the railway vehicle braking system, a hollow piston assembly which is mounted for reciprocal movement within the cy... | 08/07/2001 |
| 4817767 | Hydraulic brake system for automotive vehicles A hydraulic brake system for automotive vehicles with a master brake cylinder (1) connected to an unpressurized reservoir and with a brake line (13, 14) connected to a working chamber (4, 5) of the master brake cylinder and leading to pressure control val... | 04/04/1989 |
| 4746174 | Method and brake system for traction slip control For traction slip control, the wheel brakes (13, 14) of the driven wheels (VR, VL) are connected to the auxiliary-pressure source (5, 6) of the brake system by electromagnetically actuatable multidirectional control valves (E11, E12). In an initial phase ... | 05/24/1988 |
| 4592597 | Hydraulic brake for vehicles Hydraulic vehicle brake comprising a hydraulic accumulator (1), a brake valve adjustment device (4) supplied thereby, and a brake pressure line section (7) to the brake cylinders attached to the latter via an emergency brake valve (6). In the emergency br... | 06/03/1986 |
| 4496033 | Dual piston actuator A pair of axially aligned and nested pistons are mounted in a pressure sealed arrangement within the bore of a pressure housing. A primary piston is moved in response to increasing pressure to provide an actuating output force while a secondary piston sim... | 01/29/1985 |
| 4467605 | Hydro-pneumatic actuator with automatic slack adjuster A two-stage, hydro-pneumatic actuator suitable for use as a railway vehicle brake. The hydraulic cylinder comprises a large diameter bore in which a low- and a high-pressure piston operate jointly during a first stage of operation to effect a high volumet... | 08/28/1984 |
| 4404803 | Brake unit with a hydraulic boosting device A brake unit comprising a hydraulic booster unit connected to hydraulic auxiliary energy and controllable by a brake pedal via a control piston drives a master brake cylinder unit to supply brake pressure to wheel brake cylinders through at least one hydr... | 09/20/1983 |
| 4392558 | Actuator mechanisms for vehicle brakes The present invention provides an actuator mechanism comprising an axially rotatable actuator shaft and an actuator member which, in use, can be moved axially to actuate a brake. The actuator shaft and actuator member are interconnected by an assembly whi... | 07/12/1983 |
| 4295548 | Brake actuator A helical thrust bearing (14) is arranged between two rotatable cam components (12 and 13) of a brake actuator. The cam component (13) is turned first while the brake slack is being taken up and the brake-applying force is relatively low, the reaction to ... | 10/20/1981 |
| 4225022 | Brake booster A brake booster includes a booster piston adapted to be acted upon by the pressure fluid metered through a valve device and displacing a master cylinder piston. A pressure chamber is formed between the booster piston and the master cylinder piston. An add... | 09/30/1980 |
