Abstract
1,266,087. Hydraulic reciprocating motors. TRACTEL S.A. June 12, 1970 [June 13, 1969], No.28446/70. Heading F1A. A hydraulic actuator comprises a piston 8 reciprocable in a cylinder 1 and a reversing valve comprising a spool 20 which is reversed at the end of each stroke by a piston rod abutment 30 or 31 engaging a sleeve 26 or 27 on valve-actuating rod 23 to compress a spring 32 which, when sufficiently compressed, overcomes a detent mechanism 33 to effect rapid reversal of the valve. The detent mechanism comprises balls 33 biased radially outwardly by spring-loaded member 34 and engageable in groove 36 or 37 at either end of the valve spool movement. In the differential piston arrangement shown, supply pressure is continuously applied to the piston rod side of the piston via ports at the right hand end of the cylinder, Fig.2 (not shown) from an inlet 7 opening into annular space 6 between cylinder 1 and casing 5. The valve spool connects working space 12 to supply and exhaust via ports 18, 19, 22, and 21, 16, 17, respectively, the supply and exhaust connections overlapping during valve reversal to prevent pressure build-up. A pressure-relief valve 39 acts to connect the inlet to exhaust. The actuator alternatively may be double-acting or single-acting.
