MULTIPLIER Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: invention is designed for use in devices where multiplication of command effort is required. Used as working body in proposed device is set of equal diameter balls made of elastic material with antifriction coating. Piston is made hollow, being installed in housing to form space between its crown and bottom of housing which is made elastic, for instance, owing to spring-loaded support fitted-on. Piston crown in provided with central hole in which check valve is installed to deliver balls from its space into space between piston crown and bottom of housing, and side hole to return balls into piston space. Distributor is installed in lower space of piston provided with central and side holes with bypass valve in central hole. Bypass valve has disk with hole aligning with one of side holes of distributor and side hole of piston crown to return balls into piston space. Rocker is hinge-connected with plunger found in distributing valve central hole for shifting each ball delivered through other side hole of distributor. Spring with pusher to press balls is installed in piston space.

EFFECT: simplified process of manufacture and cost of device owing to dispensing with sealing members required when hydraulic mixture is used as working medium.
