GAS DRIVE WITH EFFICIENT SELECTOR VALVE

摘要

FIELD: machine building. ^ SUBSTANCE: proposed drive comprises movable case with cylindrical chamber, piston with rod to divide said chamber into auxiliary chamber communicated with gas source on rod side and working chamber on opposite side, selector valve with inlet and outlet control valves arranged aligned with cylindrical chamber to separate working chamber from gas source by inlet seat and inlet gate. Said working chamber is separated from atmosphere by outlet seat and outlet gate coupled with inlet gate. Proposed device comprises also double-ended control device with moving link. Selector valve outlet seat is made in end face of tappet added on piston rod side to communicate with atmosphere via channel in said tappet articulated with control device moving link to interact with outlet gate made integral with inlet gate. ^ EFFECT: ease of manufacture. ^ 2 cl, 2 dwg
