Abstract: A hydraulic pump includes a pump module and a main housing, wherein the pump module has a pump housing and a cover. A pump element is arranged in the pump housing and is connected to a rotor arranged outside the pump housing, and the cover is latched to the pump housing by means of a first detent connection. The main housing has a stator, within which the rotor is arranged, and the main housing is latched to the cover by means of a second detent connection.

Abstract: A pump unit for clutch actuation, having a high-pressure port for clutch actuation, a low-pressure port for a lubricant flow, a single drive motor and a dual pump, which is driven by the drive motor and has a high-pressure outlet, which is connected to the high-pressure port with a high-pressure line, and a low-pressure outlet, which is connected to the low-pressure port with a low-pressure line, wherein a prefilling line which leads from the low-pressure line to the high-pressure line is provided.

Abstract: An oil supply system for a machine, such as for a power unit of a motor vehicle, with a module body made of plastic including a collection tank which is divided into a prechamber and a main chamber. A predelivery pump can extract oil from the prechamber and pump it into the main chamber, a main delivery pump can extract oil from the main chamber and pump it to the machine, and a return line can return oil from the machine to the prechamber and/or the main chamber. A power unit for a motor vehicle can include such an oil supply system, wherein a predelivery suction opening is arranged on the floor of the prechamber and a main delivery suction opening is arranged on the floor of the main chamber, and the power unit is configured to be mounted in the motor vehicle with an orientation such that a line running through the two suction openings is arranged approximately parallel to the transverse axis of the vehicle.

Abstract: A hydraulic assembly with a lubricant output, a control output and a pump which can supply a hydraulic fluid flow to the lubricant output and the control output. A switching valve with structurally predefined hysteresis is arranged between a pump output and the control output of the hydraulic assembly. Depending on the pressure in the branch between the pump output and the control output, the valve can be switched between an open position in which the control output is connected to the pump output, and a blocking position in which the control output is blocked off. The switching valve switches from the open position to the blocking position when the pressure provided by the pump exceeds an upper switching threshold, and returns from the blocking position to the open position when the pressure provided by the pump falls below a lower switching threshold. A clutch can be switched by means of such a hydraulic assembly, and a method for actuating the clutch.
