PNEUMOHYDRAULIC AMPLIFIER OF VEHICLE CLUTCH LINKAGE Russian patent published in 2017 - IPC B60K23/00 

FIELD: transportation.

SUBSTANCE: invention relates to a pneumohydraulic amplifier of a vehicle clutch linkage. The pneumohydraulic amplifier comprises a power element and a control unit. The control unit comprises a tracking device installed in parallel to axes of fastening bolts that creates a hydraulic cavity with the control unit body, a pneumatic cavity formed by a tracking device, a control unit body and a two-seat valve. The tracking device comprises for automatic variation of air pressure at a hydraulic-pneumatic piston. The tracking device is spring-loaded against the body and contacts with the two-seat valve. One seat of the two-seat valve is spring-loaded in respect to the body, and the other one is formed by the tracking device. The power element comprises a hydraulic-pneumatic piston, which is movably compacted in the body and may move in the axial direction. Guide supports are permanently arranged at invariable distance between each other and are installed on the hydraulic-pneumatic piston. The hydraulic-pneumatic piston of the power element forms two cavities - a hydraulic and a pneumatic one.

EFFECT: higher device reliability.
