Appl. No.:

09/871572

Inventors:

Jamshid Kargar Moradmand - Dayton OH
Robert Alan Neal - Dayton OH

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

F16F 934

US Classification:

18832214

Abstract:

A modular blow-off base valve is provided for a vehicle twin tube damper in which a valve body is inserted into the end of an inner damper tube. The valve body has a central opening into which is inserted a valve cage assembly. The valve cage assembly includes a valve cage tubular member having a blow-off valve opening which is pressed into the central opening. A valve stem forming a valve seat with the blow-off valve opening is biased into a closed position by a helical spring seated against the underside of the valve stem at one end and a spring retainer fastened to the bottom of the valve cage at its other end. An annular bleed disc, intake disc and washer disc fit over the tubular member and cover rebound openings in the valve body. When the valve cage assembly is placed into the valve bodys central opening, the washer disc biases the intake disc into sealing engagement with the rebound openings in the valve body.

International Classification:

F16F 9348

US Classification:

1882825, 18832215

Abstract:

A vehicle damper includes a valve having of an imperforate, deflectable variable orifice disk with an outer periphery that is only partially clamped against a valve seat, during low velocity operation of the damper, by a variable orifice support disk having an outer periphery that is not coextensive with the outer periphery of the variable orifice disk. The portion of the outer periphery of the variable orifice disk that is not clamped against the valve seat deflects away from the valve seat during low velocity operation of the damper, in response to force on the variable orifice plate generated by pressure of fluid in flow apertures closed off by the variable orifice plate, to provide a variable orifice for fluid flow through the valve and digressive performance of the damper. The valve may take the form of a compression or rebound valve on the piston of the vehicle damper, or a base valve in a dual tube damper. The valve may take the form of a blow-off valve, a deflecting disk valve, a combination blow-off deflecting disk valve, or as part of other types of valves suited for use in vehicle dampers.

Abstract:

A vehicular damper includes a cylinder, a piston rod in the cylinder having a hollow end defining an axial rod passage and a cylindrical piston affixed to the end of the rod dividing the cylinder into a compression chamber and a rebound chamber. A valve plate on the rod adjacent the piston has a plurality of soft channels extending from an outer end at the rebound chamber to an inner end at the axial rod passage and a solenoid actuated cylinder in the rod passage is movable to open and close the inner ends of the soft channels. A bi-directional working disc contacts with the soft channels outer ends to provide damping in rebound and compression when the solenoid valve is open. In contrast, the piston has a plurality of firm rebound channels and a like plurality of firm compression channels extending therethrough with a uni-directional rebound working disc in valve contact with the outlet of the rebound chambers and a uni-directional compression working disc in valve contact with the outlet of the compression chambers. The damper provides valved parallel flow between compression and rebound chambers through the soft channels and through the firm channels with independent spring rate control through the firm rebound and compression channels.

International Classification:

B60T008/40

US Classification:

3031162, 3031164

Abstract:

First and second pumps are integral in that the pumps are driven by a common motor. The first pump is driven in pumping motion by an eccentric disposed on the motor shaft and the second pump is driven in pumping motion by an end of the motor shaft. The first pump can be an ABS pump and the second pump can be a pre-charge pump. The first and second pumps can be disposed in a common block housing and the common block housing can define a fluid path extending from the outlet of the second pump to the inlet of the first pump. A third pump can be susbtantially similar to the first pump and be disposed on an opposite side of the shaft as the first pump. The third pump can be driven in pumping motion by the eccentric. A separate feed line can be directed from the reservoir of the brake system to the second pump to improve performance.

International Classification:

F04B 19/00

US Classification:

417470, 417471, 417273, 417540, 417570

Abstract:

A pump used in vehicle controlled braking systems provides a reverse direction of flow through a cylinder bore of the pump and utilizes an inlet check valve located outside of the piston at the end of the cylinder bore opposite the piston, in conjunction with an outlet check valve located in an outlet extending through a sidewall of the cylinder bore of the pump. The inlet check valve is assembled and tested as a module prior to being installed in the pump. A fluid reservoir, having a movable wall, is connected to the inlet to facilitate priming the pump module. The piston is driven by a self-supporting drive apparatus with an eccentric element affixed to a stub shaft, or by other forms of a drive apparatus having an eccentric element fixed to a motor drive shaft.

International Classification:

F16F009/34

US Classification:

188/282100

Abstract:

A vehicle damper includes a valve having a flanged spring seat for clamping a floating orifice disk to a valve seat. The flanged spring seat supports and aligns the orifice disk during assembly and operation of the valve. The valve may include a bushing having a guide surface piloted into the valve seat for guiding the floating orifice disk. Piloting the guide surface into the valve seat precludes pinching or clamping of the orifice disk between the bushing and the valve seat during assembly or operation of the valve. The valve may include a low rate, high preload spring, and the floating orifice disk may include openings for passage of fluid prior to the disk lifting off the valve seat, thereby providing a digressive valve operating characteristic. The valve may be used as either a compression or a rebound valve in a vehicle damper.

US Classification:

092/072000

Abstract:

An eccentric-driven piston pump for a vehicle controlled braking system has a pump drive apparatus including a stub shaft having an eccentric journalled in a pump housing for self-supported rotation about a stub shaft axis by a first and a second rotating bearing disposed on opposite axial sides of the eccentric. The stub-shaft is operatively connected to the rotating drive shaft of a motor, and the eccentric is connected for imparting reciprocating motion to the pistons. A pair of thrust bearings including a counterweight for balancing the pump drive apparatus, are disposed on the stub shaft adjacent the eccentric at opposite axial ends thereof between the eccentric and first and second rotating bearings. The motor includes a spherical bearing for alignment of a motor drive shaft with the stub shaft, and a bushing for loosely supporting the drive shaft prior to attaching the drive shaft to the stub shaft.
