    摘要: A method and a device, respectively, for detecting the amount of wear on the carbon brush drive system of an electrically commutated d.c. motor which is used, for example, in the form of a pump motor in a motor vehicle. The d.c. motor is driven by at least two carbon brushes and includes means for detecting the generative follow-up voltage. The amount of wear on at least one carbon brush is derived from the time behavior of the generative motor voltage and displayed to the driver.

    摘要: In a hydraulic fluid pump, in particular for a vehicle brake system, having a housing and a piston that is mounted in an axially movable manner in the housing in a piston chamber. A drive moves the piston and a sealing element seals off the piston chamber in the direction of the drive. The sealing element is designed as a diaphragm that extends through the piston chamber transversely with respect to the movement direction of the piston.
