    摘要： A pressure differential indicator that eliminates the risk of providing a false positive due to fluid contamination. The invention has an electrically insulated barrier between the “hot” pin and the grounded housing without the need for a hermetic seal. The indicator can be manufactured at a greater efficiency and lower cost than is found with prior art pressure differential indicators. It has a piston that can be easily oriented to yield either a normally closed or normally open position. The indicator has at least one protrusion on a plastic overmold to engage the swage collar and resist axial rotation of the pin. A pressure seal interrupting the plastic overmold sections and exposing the underlying metal to allow for an O-ring seal with no potential leak path between plastic and metal. Finally, the pressure differential indicator has all moving components contained within a single cavity.

    摘要： A current detecting and switching apparatus that provides automatic coupling of internal components of an appliance to varying supply voltage sources to prevent components from operating at something other than their intended power rating. The switching apparatus provides automatic coupling to multi-rated internal components of the appliance instead of providing a voltage specific appliance pre-wiring of specific connections of a multi-voltage component.

    摘要： The present disclosure provides a fluid pump having a pump motor, a pump drive shaft, and a vane pump assembly. The vane pump assembly includes a pump housing with a fluid inlet port in a distal portion of the housing and a fluid outlet port in a proximate portion. A first bearing member, having a plurality of inlet orifices in flow communication with the fluid inlet port, is disposed within the housing distal portion. A cam ring is adjacent the first bearing member. A rotor, which is mounted on the pump drive shaft, is disposed within an opening in the cam ring. This rotor includes a plurality of radial slots and vanes slidably received within the slots. A second bearing member, having a plurality of outlet orifices in flow communication with the fluid outlet port, is disposed within the housing proximate portion adjacent the cam ring. An end plate is also mounted within the distal portion of the pump housing. Rotation of the rotor by the drive shaft causes fluids from the fluid inlet port to be drawn through the plurality of inlet orifices at an initial fluid pressure. The fluids are then directed along a plurality of fluid flow paths disposed between an inner surface of the cam ring and an outer surface of the rotor, and then ejected through the plurality of outlet orifices to the fluid outlet port at a second fluid pressure which is greater than the initial fluid pressure.

    摘要： A roller grill bearing assembly that can be adapted to fit on any size roller grill or roller tubes. The bearing assembly substantially increases the bearing land on the roller grill housing and increases the bearing area over the land. The bearing assembly permits the bearing apparatus to be snapped in place on the stamped opening on a sheet metal side panel as done using current manufacturing methods. Further, the bearing assembly can be produced using current manufacturing techniques without significantly changing the cost of production. Most importantly, the invention substantially increases the life span of the bearing.
