摘要： A hydraulic flow control apparatus is provided which is adapted to provide a constant pressure differential between a pump and an external load. The apparatus includes a housing, and a balance piston slideably mounted therein. The pump pressure acts to bias the piston in a direction toward a pump bypass position, and the piston is urged in the other direction and toward its operating position by the consumer pressure and a spring. Means are also provided whereby the pressure of the pump necessary to move the piston toward its bypass position and against the force of the spring, may be minimized during operation in the idling mode, to thereby minimize power consumption.

摘要： A rotary vane pump is provided which comprises a cylindrical housing, and a cylindrical rotor mounted within the housing. The rotor includes a number of radial guide slots extending axially along the length of the rotor, with each slot having a depth along at least a portion of its axial length which extends to the axis of the rotor. A blade is slideably disposed in each slot, and has a height which generally corresponds to the depth of the slot. This arrangement permits the rotor to be compact in size, and yet able to provide an adequate area of contact between the blades and rotor slots in the extended position of the blades.

摘要： An improved design for sealing and lubricating the moving parts of a rotary vane pump. An effectively operating lubricant distributing system is obtained in such a pump by forming radially extending passages through the pump drive shaft and attached rotor which connect the lubricant carrying hollow portion of the drive shaft with chambers located between the base of the vanes and the slits formed in the rotor in which the vanes radially slide. The rear bearing in which the drive shaft rotates is connected to these vane base chambers by means of an annular compartment having a lubricant duct connected thereto, thereby insuring the continuous flow of lubricant from the hollow portion of the drive shaft, through the vane base chambers and into the rear bearing. In an alternative embodiment of the present invention, the front bearing of the pump is connected with the hollow portion of the drive shaft via a lubricant passage formed on the suction side of the vanes. In addition, various designs of the above-mentioned front and rear bearing lubricant supply arrangements are also disclosed.

摘要： A positive displacement reciprocating pump for conveying a liquid or gaseous fluid is disclosed and which comprises a fluid enclosure having a movable piston means mounted therein which sealably divides the enclosure into a pumping chamber on one side and an actuating chamber on the other side. The piston means may comprise either a slideable piston or a flexible diaphragm. An inlet valve and a separate outlet valve are each connected to the pumping chamber, and a control system is provided for intermittently supplying a pressurized working fluid to the actuating chamber so as to intermittently move the piston means in the discharge direction, with the piston means being moved in the opposite or suction direction by either the pressure of the fluid being conveyed, or a suitable spring. The control system for advancing the piston means in the discharge direction includes a source of pressurized working fluid, a working fluid line extending between the source and the actuating member, and a valve operatively connected to the working fluid line for intermittently opening the line to a discharge tank or the like to release the pressure therein.

摘要： A seal for the drive shaft of a gear pump for polymeric materials dissolved in a fluid solvent is disclosed, and which is adapted to prevent the polymeric material from leaking and hardening on the drive shaft. The seal includes a pair of axially spaced apart annular packing seals surrounding the drive shaft so as to define an annular chamber, and means for supplying a pressurized shielding inert gas, such as nitrogen, into the annular chamber. An outlet line is connected to the lowest portion of the annular space and leads to an air tight container which also contains a shielding inert atmosphere, and such that any polymeric material which leaks along the drive shaft and enters the annular chamber remains in solution, and is withdrawn into the air tight container. A valve is also provided on the container for periodically draining the withdrawn polymeric material therefrom. The shielding inert atmosphere in the annular chamber and the container prevents the polymeric material from hardening, which can lead to the galling or scoring of the packing seals.

摘要： A rotary vane pump is disclosed which comprises a cylindrical housing, and a cylindrical rotor eccentrically mounted for rotation within the housing. The rotor includes a slot mounting a pair of oppositely oriented hook-shaped vanes, so as to define a hook space adjacent each end of the overlying vanes. A fluid, such as lubricating oil, is delivered to each hook space during that portion of its rotation shortly before its bottom dead center position, and the delivered fluid is pressurized during that portion of its rotation shortly after its bottom dead center position to assist in moving each vane outwardly from its bottom dead center position.

摘要： An improved design of a rotary vane-type vacuum pump which prevents the oil used to lubricate the moving parts of the pump from entering the intake line of a connected vacuum chamber. The improvement comprises forming the inlet port in the front face of the cover plate which seals the end of the rotor casing. Filters are positioned in the intake port to catch any oil flowing along the inner wall of the intake port and to condense any oil foam entering therein. In order to facilitate the condensing of the oil foam, the inlet port is divided into two connected chambers, the lower of said chambers being of sufficient capacity to collect said oil foam flowing from the pump during its operation. A check valve is also positioned in the inlet port ahead of said filters in order to prevent the vacuum pressure in the vacuum chamber and intake line from dissipating through the pump and oil mist being drawn into the intake port when the pump is stopped.

摘要： A hydraulic gear pump for the oil lubrication system of an automobile engine is disclosed, and wherein the meshing teeth of the gears define fluid cells which are expanded in the intake portion and receive the fluid from an inlet, and then compressed in the discharge portion to expel the fluid. The inlet to the pump includes at least two parallel fluid lines which are each connected to a tank. A pressure controlled valve is connected to one or both of the fluid lines, and during the normal operating range of output pressure, the valve is controlled by the pressure in the pump discharge chamber so as to decrease the flow through the lines from a maximum flow rate to a lower flow rate as the output pressure increases. In the event the engine and oil are cold, the output pressure will increase beyond the normal operating range, since the oil consumption is small. To heat this oil, the valve also includes means for throttling a portion of the output of the pump when the output pressure reaches a predetermined relatively high relief pressure which is greater than the normal operating pressure, and this throttling serves to rapidly increase the temperature of the oil. Also, the inlet fluid lines are designed to provide a flow rate during such throttling which is at least about 30% of the maximum flow rate during normal operation, to thereby assure sufficient flow for the throttling function.
摘要翻译：公开了一种用于汽车发动机的油润滑系统的液压齿轮泵，其中齿轮的啮合齿限定了在进气部分中膨胀并从入口接收流体的流体单元，然后在排出部分压缩至排出流体。泵的入口包括至少两个平行的流体管线，每个流体管线连接到罐。压力控制阀连接到一条或两条流体管线，在输出压力的正常操作范围内，阀门由泵排出室内的压力控制，以便从最大流量减少流经管路的流量随着输出压力的增加而降低流量。在发动机和油冷的情况下，由于油耗小，输出压力将增加超出正常工作范围。为了加热该油，该阀还包括用于当输出压力达到比正常操作压力高的预定相对高的溢流压力时节流泵输出的一部分的装置，并且该节流用于快速提高油。此外，入口流体管线被设计成在这种节流期间提供流量，其在正常操作期间为最大流量的至少约30％，从而确保用于节流功能的足够的流量。
