PASSIVE PISTON HYDRAULIC DEVICE WITH PARTITION

摘要

A hydraulic device having: a housing; a bore of the housing having a first piston positioned therein for a first reciprocal motion within the bore along a bore axis; a mechanical element coupled to the first piston for either driving the first reciprocal motion or being driven by the first reciprocal motion; a second piston positioned in the bore for a second reciprocal motion within the bore along the bore axis; a hydraulic fluid chamber of the bore positioned between the first piston and the second piston, the hydraulic fluid chamber having a hydraulic fluid inlet and a hydraulic fluid outlet; a chamber of the bore positioned between the second piston and a wall of the housing, the chamber for having a resilient element therein; a separator partition dividing the hydraulic fluid chamber into a first hydraulic fluid chamber and a second hydraulic fluid chamber, the separator partition positioned in the bore between the hydraulic fluid inlet and the second piston, the separator partition having a first fluid passageway for fluidly coupling the first hydraulic fluid chamber with the second hydraulic fluid chamber; and a valve for controlling flow in the first fluid passageway of hydraulic fluid between the first hydraulic fluid chamber and the second hydraulic fluid chamber.
