    摘要： A master cylinder for use in the power train of a motor vehicle to actuate the brakes or the friction clutch is designed to avoid the generation of screeching noise and/or the transmission of stray movements to the piston rod in response to shifting of the piston relative to the housing and relative to the sealing element(s) between the piston and the housing. This can be accomplished by causing the piston to turn relative to the housing and the sealing element(s) during axial movement in the housing and/or by installing one or more dampers between the piston and the housing and/or between the piston and the piston rod. The dampers can constitute separately produced parts and/or specially configured and/or finished surfaces provided on the piston and contacting the housing and/or the sealing element(s). The invention also relates to improvements in the configuration and/or the material(s) of the piston.

    摘要： A master cylinder for the clutch or brake of a motor vehicle has a housing for a reciprocable piston one end of which receives the spherical head of a reciprocable piston rod. The head is held in a desired position relative to the piston by a one-piece or composite coupling device having a first section exerting a pull or bearing upon the head of the piston rod and a second section which is confined in or surrounds the end of the piston and urges the first section in a direction to hold the piston rod against axial movements relative to the piston. The coupling device and/or the piston are or can be made of a plastic material, and the connection between such parts is or can be established by snap action.

    摘要： The piston of a master cylinder in the power train of a motor vehicle is made, at least in part, of a thermosetting plastic material and cooperates with one or more annular seals to ensure that a source of hydraulic fluid is communicatively connected with the chamber in the housing of the master cylinder when the piston is moved by one or more springs or otherwise in a sense to increase the volume of the chamber. When a pedal or another actuator causes the piston to expel pressurized fluid from the master cylinder into a slave cylinder, the seal or seals cooperates or cooperate with the housing and/or with the piston of the master cylinder to seal the source from the chamber of the master cylinder. The slave cylinder can actuate the friction clutch between the prime mover and the transmission in the power train of the motor vehicle. The piston of the master cylinder is reciprocable by or with a piston rod by way of a ball and socket joint wherein the ball of the piston rod is held against unintentional extraction from the socket of a connector forming part of or being anchored in the piston.

    摘要： The present invention relates to a hydraulic system, in particular for motor vehicles, including a master cylinder having a housing, a piston which is axially movably disposed therein, which bounds a pressure chamber filled with a hydraulic fluid, and which, upon actuation of the master cylinder, is axially moved by a piston rod acting upon the piston, thereby pressurizing the hydraulic fluid; further including a slave cylinder and a pressure-medium line connecting the cylinders; the master cylinder having an adapter for detachable connection to the pressure-medium line. The objective of improving the connection between the pressure-medium line and the adapter is achieved in that the adapter includes a sleeve made of a metal.
