Abstract: A brake valve has a main body, a shaft movable within the main body, a spool plate, a first spring and a second spring arranged within the main body. The spool plate is movable between a release configuration and a brake configuration where the shaft is adapted to be linked with a first actuator configured to slide the shaft. The brake valve has a command fluid port connected to a brake chamber. A valve ring defines the brake chamber with the main body and the shaft. The valve ring is configured to, when a pilot pressure is applied in the brake chamber, move the shaft towards the actuated position or push the second spring so as to move the spool plate towards the brake configuration.

Abstract: A pulsation damper for damping pressure medium vibrations in a hydraulic system, has a membrane within a bore of a housing, which membrane is exposed to the pressure medium on its one side and faces a gas-filled cavity inside the housing on its other side, the bore of which is closed by means of a plug. The membrane, in conjunction with the plug and a hollow-cylindrical support body, forms an independently handleable, functionally pre-testable assembly, for which purpose the membrane is substantially cup-shaped, and the support body extends into it.

Abstract: A method for controlling a pedal lever of a hydraulic power brake for an at least partially automated mobile platform. In the method, the pedal lever acts mechanically on a master brake cylinder, and the pedal lever is mechanically coupled to an actuator. The method includes: providing a first signal to a control unit for the power brake for the purpose of controlling the pedal lever so as to move same into a passive position; establishing a first hydraulic connection between the master brake cylinder and a compensating volume; and transferring a first hydraulic volume of the master brake cylinder into the compensating volume by means of the actuator acting on the pedal lever in order to control the pedal lever so as to move same into a passive position.

Abstract: A fluid container for supplying a consuming device with a working fluid, including at least one connector piece having a shut-off valve arranged therein for preventing undesired escaping of the working fluid from the fluid container. In order to increase safety against undesired emptying of the fluid container, it is provided that the valve closure body, in the closed state of the shut-off valve, is accommodated in the fluid container completely inside a contour formed by an outer edge of the connector piece, and provision is made, for support against the valve closure body, of a support, which, upon insertion of the connector piece into the receiving seat, engages at least regionally into the connecting duct and in this way displaces the valve closure body in the connecting duct.

Abstract: Brake fluid reservoir valve for installation in the reservoir's outlet tube. It includes an outer sleeve fixed in the reservoir tube and equipped with an outer stop and a hollow piston housed in the sleeve. The top of the piston is closed and bordered by a groove accommodating an o-ring seal that rests upon the upper edge of the sleeve whenever the piston enters the sleeve. The piston has windows beneath the groove communicating with the interior of the piston and lugs near its lower extremity. Openings are provided in the extension of the piston beneath the lugs. A compression spring is inserted between the piston and the outer sleeve, between the stop and the lugs.

Abstract: An electrohydraulic transmission control system having a parking lock valve by which a parking lock cylinder of a parking lock device can be charged with an actuation pressure adjustable in an operating-state-dependent manner by at least one pilot pressure adjustable in the region of an electrohydraulic pressure adjuster and/or one pressure source. Above a defined actuation pressure level, the parking lock valve is held in a defined operating state in which the actuation pressure can be applied to the parking lock cylinder. The actuation and pilot pressures can be applied to a valve device such that when the actuation and pilot pressure levels approximately correspond to one another, the region of the control system which conducts the actuation pressure is operatively connected, upstream of the parking lock valve, to a pressure region in the region of the valve device with a pressure lower than the defined actuation pressure level.
