  • Patent number: 11591988
    Abstract: A valve, such as a throttle valve plate, which is suitable for use with a throttle assembly, and is able to withstand a backpressure test. The throttle valve plate includes a flat plate, and a plastic material overmolded onto a portion of the valve plate. The plate includes at least one rib, and may include a plurality of ribs, allowing for a thinner and lighter weight plate which is manufactured at a lower cost. The valve may also be a two-piece valve plate having an overlap portion. The two pieces of the valve plate overlap at the portion of the valve plate which interfaces with the shaft of the throttle assembly. The remaining portion of the plate surface includes at least one ribbed feature, and may include a plurality of ribbed features which reduce material usage and therefore reduce weight and cost, but also provide the required strength and rigidity.

  • Patent number: 6158299
    Abstract: A pedal assembly includes a housing (16) and a pedal arm (14) pivotally connected to the housing (16) with a first end supporting a pedal pad (12) and a second end forming a pedal pivot arm (26). The pedal pivot arm (26) has at least one cam lobe (38) extending therefrom and the housing (16) has a cylindrical collar portion (30) recessed in the housing (16) for receiving and retaining at least one coil spring (24). The interaction of the spring (24) between the pedal pivot arm (26) and the collar portion (30) generates a hysteresis effect. The collar portion (30) has a notch (32) extending through the side wall of the housing (16). The coil spring (24) has a first distal end (34) seated in the notch (32) and a second distal end (36) that is in bias contact with the cam lobe (38).

  • Patent number: 5226559
    Abstract: With regards to a vehicle storage area it is common for dropping debris, from the stored vehicle, to contaminate and/or deteriorate the vehicle storage area floor surface. In this invention, a vehicle track, when suitably placed in a vehicle storage area, provides a means of collecting and removing dropping debris from a stored vehicle thereby reducing contamination and/or deterioration of the vehicle storage area floor surface. In addition, said vehicle track aids in the reproducible placement of the stored vehicle in the vehicle storage area.

  • Patent number: 4869461
    Abstract: A flow rate valve comprising a non-magnetic housing comprising a central cavity and a pressure chamber, first and second ports extending into the pressure chamber, the interior end of the first port forming a valve seat. A bobbin is received within the cavity including a coil and a central blind bore enclosed at one end. The bobbin and housing including opposingly situated circumferential grooves. An armature assembly comprising a cylindrical armature within the bore, and a valve element movable with the armature between first and second positions, for opening and closing the valve seat and a motion limiter for limiting armature motion to prevent same from impacting the bottom of the bore in response to a magnetic field generated by the coil.
