摘要： A hydraulic power pack having a prime mover driving a plurality of hydraulic pumps, a hydraulic circuit including a reservoir connected to an inlet of said pumps, an outlet circuit from said pumps, one or more pressure relief valves in the outlet circuit and a plurality of external connectors on the outlet circuit. The connectors and the relief valves are arranged so that different hydraulic flow and pressure characteristics may be obtained from each connector. Each connector has a flow and a return line, the latter being connected to the reservoir. Valves provided in the hydraulic circuit are responsive to zero flow in the return line of each connector and are adapted to divert the hydraulic flow directly to the reservoir without restriction.

摘要： A hydraulic power pack having a framework, a prime mover driving a hydraulic pump, a hydraulic circuit including a reservoir and flow and return connectors. The power pack also includes an oil cooling system comprising a thermostatically operated valve and an oil cooler in the hydraulic circuit. The valve diverts flow of fluid to the oil cooler when the temperature of the fluid rises above a predetermined limit, before returning the fluid to the reservoir. The oil cooler has a pair of heat exchangers mounted at the respective outlets of a double acting centrifugal fan directly coupled to and driven by the prime mover.

摘要： A pump jack, such as the type capable of use in pumping crude oil from an oil well, the pump jack including a double acting piston and cylinder motor with the piston rod of the motor being adapted to be connected to the polished rod projecting upwardly from a well head. A variable displacement hydraulic pump, which is driven by a motor or engine, is included in a closed hydraulic loop wherein conduits are connected to a pair of output ports of the pump. A pump control means controls the direction and volume of flow in the loop so as to establish the stroke of the piston rod. A compressible fluid counterbalance is provided for accumulation of energy during a down stroke of the piston rod so that the energy may be returned to the piston during the up stroke. An economical and versatile unit may be produced by mounting a counterbalance cylinder coaxially above the motor and providing the counterbalance with an additional closed chamber in fluid communication with a charged chamber of the counterbalance. The additional chamber may be provided in hollow structural members forming a support portion of a pump jack tower. The tower can be mounted on a portable base or deck by way of a pivot connection so that the tower can be swung down to a horizontal transportation position.

摘要： A closed-loop hydrostatic drive unit having a variable displacement fluid pump driven by an electric motor for generating high-pressure fluid adapted to be communicated to a fluid motor and returned to the fluid pump via a high-pressure filter. The closed-loop hydrostatic drive unit is mounted to a rectangularly-shaped reservoir housing having upper and bottom surfaces connected by side walls and end walls to define therein a chamber for the storage of fluid at a low pressure which is communicated to the fluid pump via a charge pump and suitable conduits and check valves. In a first embodiment of the invention the interior of the reservoir housing is divided by means of a partition to define the fluid-holding chamber, while the remaining portion of the reservoir housing defines a separate chamber for the mounting and storage of the high-pressure filter and/or other selected fluid power components. In a second embodiment of the invention the housing walls define the fluid holding chamber while the high-pressure fluid filter housing extends into and is stored within the low-pressure fluid holding chamber.

摘要： A hydrostatic transmission is disclosed which includes a pump assembly in which a main pump, a charge pump, and an auxiliary pump are commonly housed and are drivingly connected to a single shaft assembly. An external fluid connection is provided through which fluid is directed from the auxiliary pump to a power take off, and valving is provided to short circuit the auxiliary pump when power is not demanded. Means of controlling the rate of operation of the valve are also provided to prevent excessive pressure rise rates at the outlet of the auxiliary pump upon actuation of the valving.
