    摘要: A method and a device for the hydraulic actuation of a clutch operatively connected to a clutch receiver cylinder (6), especially for automobiles, are disclosed, in which, in a servo circuit (S), a servo pressure is generated, which serves for the hydraulic governing of a clutch transmitter cylinder (2), in order to generate in a pressure circuit (D) a working pressure, which is applied to the clutch receiver cylinder (6), or is applied directly to the clutch receiver cylinder (6), in order to create there a force required for disengaging the clutch. According to the invention, the servo pressure for disengaging and engaging the clutch is adjusted in defined manner in the servo circuit (S), for which purpose the servo circuit (S) comprises a proportional valve (8, 8'). As a result, with technical equipment at low cost, an automated actuation with improved response and operational behaviour of the clutch is made possible. Furthermore, a method and a device for gear-shifting a mechanical gear are disclosed, in which the servo pressure of the clutch disengagement is used for shifting the clutch sleeves of the mechanical gear.

    摘要: A hydraulic cylinder, preferably for use as a master or slave brake cylinder or in a hydraulic clutch system, maintains in a simple and inexpensive manner through the use of eccentric bushings the stroke length of the piston rod. The distance between the attachment lug and the attachment point determines the stroke length and is varied by adjusting the narrow tolerance of each bushing.

    摘要: In order to determine the boiling point of a liquid, especially a nonaqueous one such as a brake fluid, a device suspended in a body of that liquid--e.g. in a reservoir supplying fluid to a brake cylinder--forms a narrow chamber which is downwardly open and upwardly closed and which contains means for heating the liquid in that chamber and measuring its temperature; the two functions can be simultaneously performed by a thermistor. When the boiling point is reached and the liquid in the chamber is vaporized, a lessening of the heat conduction to the main body of liquid results in a steep rise in temperature; the boiling point marked by this event can be read on a meter and/or qualitatively indicated by differently colored lights, for example. An excessive temperature rise early in the test will also show an unduly low liquid level in the reservoir.

    摘要: In order to determine the boiling point of a liquid, especially a nonaqueous one such as a brake fluid, a device suspended in a body of that liquid--e.g. in a reservoir supplying fluid to a brake cylinder--forms a narrow chamber which is open at the bottom and the top and which contains means for heating the liquid in that chamber and measuring its temperature; the two functions can be simultaneously performed by a thermistor. When the boiling point is reached and the liquid in the chamber is vaporized, partial evaporation of that liquid and replacement thereof by fresh liquid from the main body results in a leveling of the temperature curve; the boiling point marked by this event can be read on a meter and/or qualitatively indicated by differently colored lights, for example. An excessive temperature rise early in the test will also show an unduly low liquid level in the reservoir.
