  • Patent number: 11719239
    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.

  • Publication number: 20230088401
    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.
