摘要： A piston-in-sleeve accumulator includes a cleaning element positioned on the piston and configured to remove and prevent debris from lodging between the piston and a cylindrical nonpermeable sleeve within which the piston slides. A seal on the piston is positioned to engage an opposing surface in the event of a leak, and thereby prevent the possibility of a complete drainage of pressurized fluid from occurring through the accumulator's fluid port. A position contactor switch is further provided to signal position of the piston within the accumulator.

摘要： Example energy storage systems (20, 20′, 20″) comprises a fluid circuit (22, 22′, 22″) and an electrical unit (24, 24′, 24″) configured to operate as a motor in a first phase of operation and to operate as a generator in a second phase of operation. The fluid circuit (22, 22′, 22″) comprises a first fluid container (30, 30′, 30″) situated so content of the first fluid container experiences a first pressure level; a tank (32, 32′, 32″) having its content at a second pressure level (the second pressure level being less than the first pressure level): and, a first hydraulic motor/pump unit (34, 134, 34″) connected to communicate a first working fluid between the tank and the first fluid container. In the first phase of operation electricity is supplied to the first hydraulic/motor unit (34, 134, 34″) whereby the first hydraulic/motor unit transmits the first working fluid from the tank into the first fluid container (30, 30′, 30″). In the second phase of operation pressurized first working fluid in the first fluid container (30, 30′, 30″) is transmitted from the first fluid container through the first hydraulic/motor unit 34, 134, 34″) to the tank (32, 32′, 32″), thereby causing the electrical unit (24, 24′, 24″) to generate electricity.

摘要： An auxiliary energy-accumulation and flow-enhancement device for a hydraulic system of a concrete pump is provided. The device includes a connection oil passage 1 having an input end P and an output end B. A check valve 11 is disposed in the oil passage between the input end P and the output end B, and an energy accumulator 10 and an overflow valve 12 having an output end T are connected to the oil passage between the check valve 11 and the input end P. Pressure oil enters from the input end P, the energy accumulator accumulates energy, and power oil is output through the check valve 11. An oil passage pressure of the output end B controls an energy accumulation state of the energy accumulator 10. The overflow valve 12 sets an overflow pressure, and overflowed hydraulic oil flows back to an oil tank from an output end T. In the course of reversing the oil passage of a distribution valve of a working oil passage device, the auxiliary energy-accumulation and flow-enhancement device releases a corresponding amount of power oil for supplementation. When the oil passage of the distribution valve is not reversed, the auxiliary energy-accumulation and flow-enhancement device also provides the power oil to the working oil passage device. Therefore, the technical solution of the auxiliary energy-accumulation and flow-enhancement device is reliable, and the oil pump operates stably.

摘要： A fail-safe system for a hybrid vehicle employing an over-center variable-displacement hydraulic motor includes an actuator configured to stroke the motor to a zero angle if each of two control ports is supplied with fluid at an equal pressure. A control valve is configured, in the event of loss of power to the valve, to default to a position in which high-pressure fluid is supplied to both control ports. A pilot-controlled check valve is coupled between high- and low-pressure ports of the motor such that, during normal operation, passage of fluid through the check valve from the high-pressure port to the low-pressure port is checked, while passage of fluid through the check valve from the second port to the first port is enabled. When the pilot control is activated, passage of fluid in the opposite direction is also enabled.

摘要： A process is described for actuating a hydraulic storage device (5) of a transmission unit comprising a storage space (9) whose volume can be varied between a minimum and a maximum. The volume of the storage space (9) can be changed from minimum to maximum by acting upon the storage space (9) with pressurized hydraulic fluid from a pressure supply (19) of the transmission unit. To overcome a restoring tendency of the hydraulic storage device (5) starting from an operating condition different from the operating condition which corresponds to minimum volume of the storage space (9) toward an operating condition which corresponds to minimum volume of the storage space (9), the pressure has to be set to a threshold value. A holding device (12) is provided to hold the hydraulic storage device (5) at least in the operating condition that corresponds to maximum volume of the storage space (9) against the said restoring tendency. According to the invention, the storage space (9) is acted upon by the pressure supply (19) with a pressure at least corresponding to the threshold value (P_schwell) until the hydraulic storage device (5) has reached the operating condition in which it can be held by the holding device (12).
