| A pair of pump bodies are disposed on the opposite sides of a rotor having vanes and a cam ring disposed in surrounding relationship with the rotor. These pump bodies serve the function of a sideplate and a pressure plate. The rotary shaft of the rotor is rotatably journaled in one of the pump bodies. A flow control valve is disposed in alignment with the axis of the other pump body, and a relief valve is disposed in surrounding relationship with the flow control valve. In this manner, the construction of various parts is simplified and the number of parts is reduced while simultaneously facilitating the machining operation. The overall length and the outer diameter as well as the weight of the pump can be reduced, advantageously reducing the manufacturing cost of the pump. The construction is further simplified by providing a cup-shaped casing around the pump body which functions as the pressure plate so that a space defined laterally of the pump body forms a pressure chamber on the discharge side of the pump. | ||||||

| A power steering pump includes a pump housing (12) and a chambered sheet metal casing (14) around the pump housing. The pump housing and casing cooperate to define a fluid reservoir (22) for the power steering system. The pump housing defines a cylindrical outer surface (30) and the casing defines a circular opening (24) through which the pump housing extends into the casing chamber. An annular groove (32) circumscribes the pump housing cylindrical surface and receives an O-ring seal (34). An annular rim (36) is defined by the casing around the opening into the chamber. The annular rim (36) extends parallel to and closely adjacent the cylindrical outer surface (30) of the pump housing and cooperates with the O-ring (34) to effect a fluid-tight seal between the pump housing and casing. The casing is rotatable relative to the pump housing so that the fluid reservoir is adjustably positionable rotatably relative to the pump housing. The casing defines a radially-extending lip (42) which circumscribes the casing opening (24). Fasteners (46, 72) carried by the pump housing (12) engage the casing lip (42) to hold the casing and pump housing together while allowing adjustable rotational positioning of the fluid reservoir relative to the pump housing. | ||||||

| A rotary positive displacement pump of the pin roller type comprising a pump housing made of aluminum having a pump chamber with the inner periphery being cylindrical, which is fixed between a pump base and a pump case, a rotor eccentrically located within the pump chamber and driven by a motor, a plurality of rollers made of synthetic resin which is inserted in clearance grooves formed on the outer periphery of the rotor, wherein a centrifugal force generated when the rotor rotates moves the rollers toward the inner wall of the pump housing thereby to form a pump operation space. | ||||||

| A rotary fluid pump has a stator housing with a generally cylindrical cavity extending therethrough and a pair of recessed end heads assembled at opposite ends of the housing to form a pump cavity therewith. A drive shaft is journalled in the end heads by bearings and extending eccentrically into the interior of the pump cavity and a rotor is mounted on the drive shaft within the pump cavity. A pair of sealing plates of different thickness are individually disposed between the ends of the stator housing and the end heads to divide the pump cavity into a pair of end chambers defined by the end head recesses and the plates and an intermediate rotor chamber defined by the plates. A plurality of vanes are slidably disposed in an equal plurality of grooves radially formed in the rotor. The drive shaft is constrained to prevent axial displacement by stoppers, washers or a combination thereof mounted on the shaft and contacting bearings that support the shaft. The bearings are fixed to one end head. | ||||||

| A motor pump comprises a DC motor unit, a pump unit and a cover housing for the motor and pump unit; the motor unit includes a cup-shaped yoke with the bottom having a bearing, and a bearing holder is fitted into an opening in the cup-shaped yoke to thereby hold an armature shaft of the motor unit in position with respect to the yoke. The pump unit has a pump stator secured to the bottom of said cup-shaped yoke and a pump rotor connected to the armature shaft by key arrangement. The pump stator has a passage communicating the gap in the key arrangement and the pump inlet. As a result, fuel in the gap is prevented from stagnating therein, thereby preventing rusting of the pump components. | ||||||
| 286 | Liquid pump, particularly a fuel-oil pump | US3791765D | 1971-10-15 | US3791765A | 1974-02-12 | HANSEN G |
| The invention relates to a pump assembly which may be utilized as a fuel oil pump and which has constructional features which minimize the possibility of air binding. The assembly has a rotating casing member in which pumping elements are housed and which is surrounded by a casing so as to form a suction chamber which surrounds the rotating casing member. The rotation of the casing member causes liquid in the suction chamber to also rotate and form a ring of liquid. The rotating casing member has an eccentrically positioned inlet which passes through the ring of liquid so formed once during each cycle of rotation and this insures the introduction of liquid, as distinguished from only air, into the inlet.

| 287 | Stack-up assembly | US3787151D | 1972-07-07 | US3787151A | 1974-01-22 | CARLSON R |
| A stack-up pump is provided with a pressure generating area ported through a pressure plate and a separator plate to a valve plate, the separator plate contacting the pressure plate on one side and open to high pressure channels on the other side whereby the separator plate is biased against the pressure plate and the pressure plate in turn against the pressure generating rotor cavity to maintain a seal. To prevent the separator plate from pressing against the pressure plate with sufficient force to bow the pressure plate and seize the rotor, the pressure plate is relieved in areas under the separator plate.

| A compact housing construction for a power booster pump of the type having a stack-up of parts forming an operative pump unit wherein first and second axially disposed housing parts together form a cylindrical housing envelope for enclosing the stack-up of parts, the parts being sized and shaped to form complementary inner and outer diameters with a seal groove and a locking groove formed therein so that one part may be inserted within the other. One of the parts has an inlet opening for connection to a top mounted or remote mounted reservoir.
