  • High pressure hydraulic distributor having a mechanically controlled discharge valve
    Patent number: 4612846
    Abstract: 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.

  • High pressure hydraulic distributor
    Patent number: 4610271
    Abstract: A high pressure hydraulic distributor with a pilot pressure generator, in which a device for reducing pressure is integrated into a distribution section of a compound high pressure hydraulic distributor. The displacement of the slide of the distributor of the section concerned modifies automatically the calibration of the pressure reducer and permits obtaining a reduced pressure which is a function of the displacement of the slide. This reduced pressure is utilized as the pilot pressure for the control means of the source of hydraulic fluid pressure which feeds the distributor.
