Abstract

Step valve for hydraulic circuits, of the type comprising a cylinder supplied with hydraulic fluid by a feed end and inside which moves a plunger provided with that of the feed end, closes giving rise to a bypass valve arranged so that, when the piston moves from its initial resting position, pressure increase at the opposite end of the cylinder, connected to the pressure chamber, while moving back the piston to its initial resting position, said valve opens and allows the pressures of both ends of the cylinder to equalize, characterized in that it is constituted by a cylindrical shank coaxial to the axis of the cylinder, which crosses the piston centrally, from part to part, the end of said shank corresponding to the chamber being provided of pressure of a perpendicular disc, of greater diameter, in whose internal face a tubular seal of stacked is supported this device surrounds the rod and is adapted to close the bypass valve when it is supported against the corresponding face of the piston, a hollow, perforated-walled hood being disposed on said inside of the plunger. A compression spring that tends to keep the valve closed. (Machine-translation by Google Translate, not legally binding)
