DEVICE FOR REGULATION OF INTERNAL COMBUSTING ENGINE BOOST PRESSURE Russian patent published in 2014 - IPC F02B37/18 F02D23/00 

FIELD: motors and pumps.

SUBSTANCE: device for regulation of ICE boost pressure comprises a bypass valve body (1) with the main duct (2), connecting exhaust manifold of the motor with the turbine entry, and bypass duct (3), connected to an atmosphere through the exhaust pipe, interconnected to each other with the opening (4), shut by a bypass valve (7), guiding bush (6) of the valve, resilient membrane (9), fixed at the valve end (7), pneumonic cell (8), connected through the tube with the motor intake manifold and spring (18). The device is equipped with a cylinder (13), fixed on a cover of the pneumonic cell (8), piston (14), resting on the spring (18), thrust ring (16) for limiting the piston stroke (14), distributing valve (21) for the working medium, control unit (22), motor load sensor (23) and air temperature transmitter (24). The guiding bush (6) of bypass valve has on internal surface a helical groove (25), and its external surface is designed ribbed.

EFFECT: correction of the load, initiating the relief of exhaust gases.
