PRINCIPAL BRAKING CYLINDER Russian patent published in 2009 - IPC B60T11/16 

FIELD: transport.

SUBSTANCE: braking cylinder housing accommodates primary and secondary pistons with springs that form the first and the second compression chambers. There is a groove between secondary piston end faces sealed relative to cylinder wall to make compensation chamber of primary compression chamber. Central bore of secondary piston houses spring-loaded valve of primary compression chamber arranged to separate these chambers. Housing bottom accommodates spring-loaded valve of secondary compression chamber with control elements mechanically coupled with secondary piston. Housing radial hole houses secondary piston rest to interact with side walls of the groove made between secondary compression piston faces. Primary compression chamber control element represents a bell crank arranged in radial hole of secondary piston. One arm of aforesaid bell crank is articulated with primary compression chamber valve follower, while another arm of the bell crank contacts secondary piston rest, when in initial position.

EFFECT: improved performances.
