Abstract:
The hydraulic energy converter can be connected to a hydraulic system. The converter comprises a manifold device for controlling hydraulic fluid flow, a controller for controlling the manifold device, and at least one accumulator connected to the manifold device, for storing hydraulic energy supplied by the hydraulic system via the manifold device.
Abstract:
A shovel includes a main pump, a hydraulic actuator, and an accumulator part. The hydraulic actuator is configured to be driven with hydraulic oil discharged by the main pump. The accumulator part is configured to store the hydraulic oil discharged from the hydraulic actuator and discharge the hydraulic oil to the intake side of the main pump.
Abstract:
A pressure supply device in accordance to one or more aspects includes an elongated body having an internal bore extending from a power end to a discharge end having a discharge port, two or more gas generators connected to the power end and a hydraulic fluid disposed in the bore between a piston and the discharge end. The ignition of one of the gas generators drives the piston to exhaust a partial volume of the hydraulic fluid that is less than the total operational volume of the hydraulic fluid under pressure to operate at a connected device.
Abstract:
A hydraulic hoselinder (20) is a hydraulic linear actuator (21) integrated into a flexible hose (22). A continuous length (45) of flexible hose (22) has a rigid fluid coupling (23) mounted at one end (27) and a rigid rod fitting (26) mounted at an opposite end (32). A cylinder rod (30) extends through the rigid rod fitting (26) and includes an eye (31) at one end (27) and a piston (33) that divides the flexible hose (22) into a extend hydraulic volume (40) and a retract volume (41). The cylinder rod (30) is movable along a straight line with respect to the rigid rod fitting (26) between a retracted position and an extended position. A majority of the active length (45) of cylinder rod (30) is positioned inside and outside of the flexible hose (22) at the retracted and extended positions, respectively.
Abstract:
The present invention relates to a hydraulic control device using a hydraulic actuator, provides a hydraulic control device using a hydraulic actuator, and comprises: a hydraulic actuator having a clearance pocket; an oil supply line and an oil discharge line which are respectively connected to said hydraulic actuator; pilot valves which are respectively connected to said oil supply line and said oil discharge line; and an accumulator which additionally supplies oil to said hydraulic actuator, wherein easy hydraulic management can be carried out and pressure can be adjusted and controlled in a more efficient and proper manner.
Abstract:
A hydraulic module designed to be mounted on a hydraulic hybrid vehicle, characterised in that it forms a rigid and compact assembly comprising a body (32) receiving the high- and low-pressure accumulators intended to supply traction motors of the vehicle, comprising a generally parallelepipedal shape, and having attachment means designed to be fixed under a floor at the rear of the vehicle.
