Title: SYSTEM FOR RECOVERING ENERGY FROM A HYDRAULIC ACTUATOR
Abstract:
The invention relates to a system (1) for recovering energy from a hydraulic actuator (2) and to a method of operating said system (1), the system (1) comprising: a hydraulic actuator (2); a source of hydraulic pressure, preferably a hydraulic pump (5), in fluid communication with the hydraulic actuator (2) for pressurizing the hydraulic actuator (2); a hydraulic accumulator assembly {15) for selectively absorbing energy from the hydraulic actuator (2) or via the hydraulic actuator (2); and a first one-way valve (17) configured to provide fluid communication between the hydraulic actuator (2) and the hydraulic accumulator assembly (15), the first one-way valve (17) configured to permit a flow of fluid through the first one-way valve (17) from the hydraulic actuator (2) to the hydraulic accumulator assembly (15), and the first one-way valve (17) configured to block a flow of fluid through the first one-way valve (17) from the hydraulic accumulator assembly (15) to the hydraulic actuator (2).
