FIVE-LINE TWO-POSITION SPOOL-TYPE ELECTROPNEUMODISTRIBUTOR FOR ONE-SIDE CONTROL OF VEHICLE DOOR DRIVE Russian patent published in 2004 - IPC

Abstract RU 2242575 C1

FIELD: transport-engineering.

SUBSTANCE: invention relates to pneumatic devices and it can be used to change direction of compressed air flows in pneumatic lines of vehicle drives. Proposed electropneumodistributor has housing, cylindrical spool, control piston, electropneumatic control valve, spool reset device, auxiliary manual mechanism, system of channels and pneumatic lines connecting electropneumatic with actuating mechanism. Cylindrical spool is made integral with control piston in form of differential spool installed in housing bores for axial displacement, and finishing of housing bore surfaces and forming of fillet radii of cutoff edges of control channels on said surfaces are made by mechanically rolling by means of freely rotating spring-loaded balls pressed to surface to be machined. Auxiliary manual control mechanism is built into differential spool control space coaxially to its position to control mechanism from vehicle door drive under action of electropneumatic distributor.

EFFECT: improved reliability, simplified design and manufacturability, provision of opening of door from passenger compartment.
