An actuation device for a hydraulic actuation system, e.g., a motor vehicle brake or an electrified clutch actuator, may include a connection for an actuation device; a pressure supply device, driven by an electromotor drive, in the form of a piston or double-stroke piston pump; a piston cylinder unit that may be actuated by means of the actuation device; and an electronic control unit. An axis of the piston cylinder unit and an axis of the pressure supply device may be arranged in parallel.

An electric component assembly includes a housing with which an electric component is fitted together, and the electric component and the housing are fixed to one side of a base body. The electric component includes a connecting terminal configured to be press-fitted in a through-hole of the control board of the housing, and a direction in which the connecting terminal is inserted into the through-hole is same as a fitting direction relative to the housing. There are provided a rib protruding from one of the electric component and the housing, and a groove portion recessed from another one of the electric component and the housing and into which the rib is press-fitted. Movement of the electric component in a direction intersecting the fitting direction and rotation of the electric component around an axis parallel to the fitting direction are restrained by the rib press-fitted into the groove portion.

In a pump arrangement for a hydraulic unit of a vehicle brake system having a pump housing and a pump piston which is guided so as to be displaceable axially back and forth in the pump housing, a damping element is provided radially between the pump piston and the pump housing. The damping element damps vibrations of the pump piston which occur during an operation of the pump arrangement.

A braking system of an industrial vehicle includes an accumulator accumulating hydraulic oil, a hydraulic oil cooler cooling the hydraulic oil, an electromagnetic switch valve switching between an oil channel for the accumulator that allows supplying the hydraulic oil from a hydraulic pump to the accumulator and an oil channel for the hydraulic cooler that allows supplying the hydraulic oil from the hydraulic pump to the hydraulic oil cooler, and a controller controlling the electromagnetic switch valve to switch from the oil channel for the hydraulic cooler to the oil channel for the accumulator with timing of an increase after a drop in an engine speed when a cargo-handling operation is detected while an oil is at a setting pressure value or less and while the engine speed is at a setting engine speed or less.

A piston pump, in particular as a pressure generator in an electronically slip-controllable vehicle brake system, includes a pump cylinder, a drivable piston, a pump working chamber, a valve space, and a valve. The drivable piston is slidably accommodated in the pump cylinder. The pump working chamber is bounded by the piston and the pump cylinder. The valve controls a supply of pressure medium to the pump working chamber. The valve has a conical valve seat and a closing element having a domed shell section that interacts with the valve seat. The valve seat surrounds the valve space, into which the closing element plunges, at least up to an imaginary center point of the domed shell section, when the valve seat is closed or open.

Provided is a hydraulic unit of a brake system including a housing; an oil supply part configured to supply oil to the housing; an oil discharge part configured to discharge the oil, supplied to the housing through the oil supply part, to the outside of the housing; and a piston movably mounted on the housing, and configured to open and close the oil supply part and the oil discharge part.
