... a brake flow regulating device for automobile based on Pascal principle.

摘要

In a clutch/brake interlock control system for a motor vehicle, brake fluid is supplied through an inlet (10), a duct (13), a valve seat (12), a chamber (24), a duct (13a) and an outlet (11), from a source to a brake cylinder, upon depression of a brake pedal. The valve seat (12) is closed by a valve closure member (5) under the action of a spring (9) to retain brake fluid in the brake cylinder and the brake applied unless the valve closure member (5) is drawn away from the seat (12) by a solenoid armature (8) which moves upwards under the action of a stronger spring (9a) when a solenoid coil (3) is deenergised. The coil is deenergised when a clutch pedal (14) is released to engage a transmission of the vehicle. This avoids premature release of the brake when a vehicle is started on a hill. IMAGE
