Abstract

1,207,418. Distributing valves. AIRMATIC VALVE lnc. May 27, 1968, No.25351/68. Heading F1M. A pneumatically actuated reciprocating,valve for alternately supplying pressure fluid to opposite ends of a power cylinder 50 or the like comprises a valve body having a bore therein, an inlet port 24 and a pair of work ports 26, 28 communicating with the bore, a valve spool 16 reciprocable in the bore and operable upon reciprocation thereof, alternately to connect each work port with the inlet port and the other work port to exhaust, means connecting the work ports to opposite ends of the power cylinder and passage means so connecting the inlet port to opposite ends of the bore to supply pressure fluid to opposite ends of the valve spool, each passage including a restricted orifice 82 therein. The valve also comprises an exhaust passage 70 communicating with each end of the bore and a normally closed poppet valve 64 in each exhaust passage, pressure responsive means 74 associated with each of the poppet valves and means connecting each work port with one of the pressure responsive means for actuating the latter. The pressure responsive means are operable upon actuation thereof to open the poppet valve associated therewith and exhaust one end of the bore thereby to permit the pressure fluid in the opposite end of the bore to shift the spool towards the one end of the bore, the pressure responsive means being operable to open their respective poppet valves only upon completion of a work stroke by the power cylinder.
