摘要： A reservoir is provided. The reservoir defines an internal storage cavity. A plurality of system connections extend through a sidewall of the reservoir defining channels fluidly communicating the internal cavity of the reservoir with the exterior of the reservoir. A valve arrangement has a valve member that operably simultaneously closes off all of the plurality of system connections to prevent fluid flow from the internal cavity through the system connections when in a closed position. The valve arrangement, when the valve member is in an open position, permits fluid flow from the internal cavity and through all of the plurality of system connections.

摘要： A rotary air motor driven hydraulic pump has separate pressure and return actuators and first and second stage eccentric driven pistons 180 degrees out of phase and driven by the motor through a gear reduction unit. The pressure and return actuators are on/off/proportional valves and the pump has two pressure relief valves with one adjustable from outside of the pump for a user to set a pressure limit of the pump. Above a certain output pressure limit, a bypass valve shunts flow in excess of that needed to precharge the second stage compression chamber from the first stage piston to an elastic reservoir from which the hydraulic fluid pumped by the pump is drawn. To make the pump stall at a certain output pressure, a pressure limiting valve can be used that cuts off the air supply to the pump at the desired output pressure.

摘要： A hydro-pneumatic system has an air powered motor driving a hydraulic pump with a pressure limiting valve that turns off air flow to the air motor when a hydraulic pressure output by the pump at a sense port of the valve reaches a certain limit. A valve element of the valve has spring, hydraulic and pneumatic sections, with an unbalanced area of the hydraulic section in a sealed pressure chamber of a cartridge that is part of the valve housing. The pneumatic section extends out one end of the cartridge to fill a bore between the air inlet and outlet ports when the pneumatic section is extended, and allow air to pass when it is retracted.

摘要： The invention provides a variable speed hydraulic pump designed to operate at a maximum horsepower throughout its pressure range by adjusting motor speed according to motor load parameters. In particular, the variable speed hydraulic pump includes a hydraulic pump unit coupled to a variable speed electric motor by a drive unit and to a hydraulic fluid tank for pressurizing and pumping hydraulic fluid when operated by the motor. A motor controller is electrically connected to the motor to supply drive signals to the motor based on electrical characteristics of the drive signals which are dependent on the load exerted on the motor. Suction from the load is provided by both the main pump and a bidirectional supercharging pump by reversing the direction of the motor and shifting a 4/3 valve to connect the main pump inlet to the load and its outlet to tank. In addition, the controller reduces the motor speed at the maximum rated pressure to just maintain the pressure, to reduce the amount of fluid pumped through the maximum pressure relief valve.

摘要： A hydraulic storage tank is provided. The hydraulic storage tank includes a storage tank, a return flow filtration chamber, a contaminant containment chamber (CCC) and a tube connecting the return flow filtration chamber with the CCC. The storage tank defines a reservoir for storing hydraulic fluid. The return flow filtration chamber is configured to house a return flow filter. The CCC includes a boundary wall bounding a cavity and a CCC outlet fluidly communicating the cavity with the reservoir. The CCC outlet is radially inward from the boundary wall. The tube defines a discharge passage fluidly connecting the filtration chamber with the cavity of the CCC and includes an inlet in fluid communication with the filtration chamber and an outlet in fluid communication with the CCC. The outlet of the tube directs fluid in angular direction about an axis defined by the contaminant containment chamber outlet.
