A hydraulics assembly, in particular for controlling the brake pressure of a wheel brake of an electronically slip-controllable brake system of a motor vehicle, includes a hydraulic block having a recess for receiving a pump element, a line connection for contacting the hydraulics assembly to the wheel brake, channels for providing the pump element with brake fluid, and a hydraulic cavity formed in the interior of the hydraulic block, which cavity is contacted with the recess for the pump element. The cavity includes a riser, which extends from the recess for the pump element in the direction toward the line connection of the hydraulic block and is contacted with the recess for the pump element. The suction line collects gas escaping from the pressure means due to temperature and/or pressure changes and improves the operating noise of the hydraulics assembly.

An example valve includes: a plurality of ports comprising: a first port, a second port, and a third port; a spool configured to block fluid flow from the first port to the third port while allowing fluid flow from the third port to the second port when the valve is in an unactuated state; a spring applying a biasing force on the spool in a proximal direction, wherein when the valve is actuated, the spool moves in a distal direction against the spring, thereby allowing fluid flow from the first port to the third port while blocking fluid flow from the third port to the second port; and a turbine configured to rotate as fluid flows from the first port to the third port when the valve is in an actuated state.

Provided is an energy storage structure, comprising a housing and a piston. An accommodating cavity and a piston cylinder part communicating with each other are arranged within the housing. The piston is slidably and sealingly arranged within the piston cylinder part for transferring impact energy. A self-pressure of an energy storage medium, arranged within the accommodating cavity and the piston cylinder part, acts on the piston, tending to push the piston to move. An energy storage structure provided by the present invention has a simple structure, is convenient for use, and can ensure that a thrust or impact force remains unchanged or slightly changes during operation, to achieve stable release of potential energy. Moreover, the adjustment of the thrust or impact force can be achieved by changing the temperature of the energy storage medium in the accommodating cavity, thereby achieving change in total impact energy of the energy storage structure.

A brake signal transmitter (10) includes a housing (11) and a liquid drainage system (20). The liquid drainage system (20) includes an opening in the housing (11) and a cover (30) that extends over or along the opening. The cover (30) includes at least one aperture that allows a liquid to be drained through the cover (30). The opening (21) of the housing (11) is arranged on a downward side of the housing (11) relative to a gravitational force the transmitter is mounted horizontally. The cover (30) may be a cap having a filter inserted therein. The filter may define a tortuous path to block ingress of water or debris into the housing. The cover may include resilient fingers that snap fit into a socket of the housing.

A working machine includes a machine body, a left traveling device located left on the machine body, a right traveling device located right on the machine body, and a controller configured or programmed to perform automatic deceleration to automatically reduce a first rotation speed of a left traveling motor and a second rotation speed of a right traveling motor by shifting a speed stage of each of the left and right traveling motors from a second speed stage to a first speed stage that is lower than the second speed stage. The controller is configured or programmed to: not perform the automatic deceleration when the first rotation speed or the second rotation speed is equal to or higher than a predetermined rotation speed; and perform the automatic deceleration when the first rotation speed and the second rotation speed are less than the predetermined rotation speed.

A fail-safe drive (1) for an actuating drive is provided, which has a cam disc (8), at least one restoring element, a counter-element (5) and an output shaft (3), with the cam disc (8) and the counter-element (5) being configured for joint conversion of an axial movement of the restoring element along the output shaft (3) into a rotational movement of the output shaft (3). The cam disc (8) has a control cam (10), the profile of which is adapted to a spring characteristic curve of the restoring element such that, in the case of activation of the failsafe drive (1), a constant output movement and/or a constant output torque can be generated.
