Title:
FLUID CIRCUIT IN CAR
Document Type and Number:
Japanese Patent JPS61211157
Kind Code:
A
Abstract:
PURPOSE:To prevent the transmission of oscillation and the generation of different noise between two cylinders by providing a parallel path section in the fluid circuit between two cylinders and arranging a check valve with a spring in the two paths so that each check valve can mutually be actuated in the reverse direction. CONSTITUTION:When a clutch pedal 13 is stepped in, oil pressure is generated in a master cylinder 11. If this oil pressure becomes higher than the actuation pressure of the check valve 17 with a spring of a path 16a, the oil pressure is transmitted to a release cylinder 12 through a metallic pipe 14, a rubber hose 15, and the path 16a and a clutch is operated. Then, when the pedal 13 is opened, the pedal 13 is returned to the original position by the oil pressure of an energization means that returns a piston rod 12a and the energization of a spring 13a. On the other hand, if the pedal 13 is not operated, a circuit that connects the master cylinder 11 and the release cylinder 12 is disconnected by the check valves 17 and 18 with the spring. As a result, the pedal 13 can be prevented from being oscillated and generating different noise.
