A power steering pump for an automotive vehicle including a housing defining a compartment, a cam plate disposed within the housing, a rotor disposed within the housing and a lower pressure plate disposed within the housing between the cam plate and a closed end of the housing. A cover sealingly engages the housing to close an open end of the housing. The cover includes under vane porting to provide a fluid path from an outlet port on the cover to the rotor.

Power steering pump

A power steering pump comprises a housing that includes a bore, a fluid discharge port that supplies pumped fluid into the bore, and a fluid bypass port for recycling excess fluid to the pumping elements. The pump outlet is at one end of the bore. A flow control valve is slideably received in the bore and regulate the size of the inlet to the fluid bypass port. The pump includes a solenoid assembly that has a plunger that is operatively connected to the flow control valve through the second end of the bore opposite the pump outlet. By adjusting the magnitude of the current to the electromagnetic coil of the solenoid assembly, the position of the flow control valve is varied to increase or decrease fluid flow to the fluid bypass port and thereby regulate the output from the pump.

Power steering pump having electronic bypass control

A power steering pump comprises, as main elements, a cam plate, a discharge cover plate and a suction cover plate that cooperate to define a cam chamber, a fluid discharge passage and fluid suction passage for the pump. The cam chamber is formed in the cam plate. The discharge cover plate includes a face that abuts a first face of the cam plate and includes a recess that cooperates with first cam plate face to define a fluid discharge passage. A suction cover plate includes a suction cover face that abuts a second face of the cam plate and comprises a recess that cooperates with the second cam plate face to define a suction passage. The power steering pump further comprises a rotor within the cam chamber and comprising slideable vanes.

An integrated, i.e unitary, rotary hydraulic vane pump assembly reduces cost and simplifies manufacturing thereof. The integrated assembly includes an electric motor, a rotary vane pump, a pump housing and an end bell. The end bell has an inlet fitting or passageway which communicates with the inlet of the rotary vane pump. The pump housing receives the vane pump and is received within the end bell. The electric motor is secured to the face of the pump housing opposite the end bell. The pump housing includes outlet passageways and a centrally disposed axial opening for receiving an output shaft of the electric motor. The rotary vane pump includes end sections and a center, cam ring section which receives a vane rotor assembly coupled to the output shaft.

A cartridge-style pump &lsqb; &rsqb; for a vehicle power steering system can be assembled, tested and shipped independently of an associated pump housing &lsqb; &rsqb;. The pump &lsqb; &rsqb; includes an upper plate &lsqb; &rsqb;, a cam plate &lsqb; &rsqb; having a bore &lsqb; &rsqb; formed therein for receipt of a rotor &lsqb; &rsqb;, and a lower plate &lsqb; &rsqb;. A plurality of alignment pins &lsqb; &rsqb; are pressed into the lower plate &lsqb; &rsqb; with the cam plate &lsqb; &rsqb; and the upper plate &lsqb; &rsqb; placed onto the alignment pins &lsqb; &rsqb; to locate the plates in their proper position. A plurality of retaining clips &lsqb; &rsqb; are placed onto a respective alignment pin &lsqb; &rsqb; to hold the pump &lsqb; &rsqb; together.

A hydraulic pump &lsqb;,&rsqb; for an electro-hydraulic power steering system is positioned in a fluid reservoir &lsqb;,&rsqb; in a pump housing &lsqb;,&rsqb;. The pump &lsqb;,&rsqb; has an upstream end &lsqb;,&rsqb; that receives fluid from a fluid source and a downstream end &lsqb;,&rsqb; that is in communication with fluid expelled from the pump &lsqb;,&rsqb;. The pump housing &lsqb;,&rsqb; has an integral dampening chamber &lsqb;,&rsqb; formed therein adjacent the downstream portion &lsqb;,&rsqb; of the pump &lsqb;,&rsqb;. The dampening chamber &lsqb;,&rsqb; helps minimize pressure pulsations before the fluid is passed through an outlet opening &lsqb;,&rsqb; in the housing &lsqb;,&rsqb; to a steering gear.

A power assisted steering system,has a control valve,, a pump,coupled to the control valve,, and a motor,coupled to the pump. A controller,is coupled to the motor. The controller generates a control signal having a voltage and a current. The controller,generates a desired motor current in response to a desired flow rate and valve angle of the control valve

Control method and apparatus for an electro-hydraulic power assisted steering system

An electro-hydraulic gear pump power pack (10), including a hydraulic pump disposed in a pump reservoir (12) and an electric motor disposed in a motor housing (14), are secured together to form a single assembly. The pump reservoir (12) and the motor housing (14) are secured together by a pair of mounting brackets (18) that also serve to attach the power pack (10) to a vehicle structure (20).
