[CN 201680039312.0] harmonic distribution radial piston hydraulic press


[CN 201680039312.0] Harmonic Distribution Radial Piston Hydraulic Press Title: Harmonic Distribution Radial Piston Hydraulic Press Application Number: CN 201680039312.0 Applicant: Pokran Hydraulic Industrial Equipment Company Application Date: 2016-7-1 Patent Type: Invention Application The hydraulic press includes a cam (4) and a cylinder with a piston (14), the piston is matched with the lobe of the cam, each lobe has two ramps (50A, 50B) extending between a top dead center arc and a bottom dead center arc (PH, PB). The cylinders are alternately connected to the supply part and the discharge part according to a sequence separated by switching phases comprising isolated phases with respect to the main pipe, the supply pipe and the discharge pipe. The angular position of the start or end point of the at least one first isolation stage relative to the respective dead center arc is different from the angular position of the start or end point of the at least second isolation stage relative to its respective dead center arc. The two dead center arcs are either top dead center arcs or bottom dead center arcs.
