Abstract (en)
[origin: US4612846A] The invention involves a new structure for a distributor for a hydraulic fluid utilization means, such as a single-acting jack, controlled by the distributor in any position. The distributor includes a spool-type valve and a hollow piston valve which is piloted by a needle valve. The needle valve and spool-type valve are both mechanically connected to a single mechanical lever.
