  • Patent number: 5984060
    Abstract: A monotube strut assembly includes a housing tube with a piston assembly fixed relative to the housing tube by a piston rod. A damper body tube is reciprocally carried in the housing tube and is slidably engaged with the piston assembly. A bearing sleeve is fixed in position within the housing tube and seals are carried at both first and second ends of the bearing sleeve. A bearing is positioned adjacent each of the first and second ends of the bearing sleeve and the bearings slidably support the damper body tube. A quantity of oil is carried between the damper body tube and the bearing sleeve providing lubrication between the bearings and the damper body tube.

  • Patent number: 5927827
    Abstract: A braking system generally provides pressure equalization between the sides of a split braking circuit. The amount of equalization provided is limited to enable the introduction of purposely induced pressure variances. A result is that unintentional pressure variations are moderated and intentional target pressure variations are easily obtainable. The braking system provides power braking operation in response to a manually actuated master cylinder. Fluid pressure is transmitted through isolation valves directly to the wheel brakes. The braking system also provides power operation in response to a powered pump. The pump delivers pressurized fluid through a controllable supply valve. When the supply valve is open, the isolation valve(s) are shifted to provide open fluid communication path between proportional pressure control valves and the wheel brakes. The pressure equalization effecting device is isolated from the master cylinder pressurized circuit during base brake operation.

  • Patent number: 5921360
    Abstract: A digressive valve for a vehicle damper provides rebound performance with a relatively high damping rate for low velocity inputs and a relatively low flow restriction operation for high velocity inputs so that a relatively firm ride with reduced impact harshness is achieved. A piston has a set of compression openings and a set of rebound openings extending through the piston from one surface, to another surface having a cavity, with an annular seat formed in the cavity. A compression valve is positioned adjacent the piston and normally substantially closes the set of compression orifices. During compression, fluid flow out from the set of compression orifices is restricted by the compression valve. Positioned in the cavity is a rebound valve with a blow-off valve having an annular surface that tightly seals against the annular seat. A spring is biased against the blow-off valve, forcing the annular surface against the annular seat under a preload.

  • Patent number: 5461938
    Abstract: A control cable end connector offering positive locking and positive sealing features for control cable connection. A connector feature is molded on the cable sleeve becoming a permanent part of the cable assembly. An acoustic cup is positioned on the connector which slides along the connector and includes two cantilevered locking hooks. The connector locates through an opening in a substantially flat portion of a wall by capturing the wall between two flanges. The acoustic cup seals the end connector area of the wall and snaps into the substantially flat wall providing a positive lock against the removal of the connector.
