  • Patent number: 6666585
    Abstract: A unitized cage for cylindrical roller bearings wherein the inner raceway of the bearing configuration may be the rotating or stationary shaft component and the outer raceway of the bearing configuration may be the rotating or stationary housing component. Thus, a bearing configuration can be generated without the need for a separate inner or outer race having inner or outer raceways. The unitized cage comprises a cage nest having end face axial projections and a cage finger ring having fingers which engage the end face axial projections to lock the cage nest into position on the cage finger ring. A plurality of cylindrical rollers can be positioned within the cage pockets of the cage nest prior to the assembly of the cage nest with the cage finger ring to generate a cylindrical roller bearing.

  • Patent number: 6321995
    Abstract: A thermostatic expansion valve for a vehicle air-conditioning system includes a valve body with a condenser passage and an evaporator passage, and a power element supported on one end of the body. The power element includes a diaphragm and a pressure pad disposed against the lower surface of the diaphragm. The pressure pad includes a valve stem engaging a valve assembly in the valve body to control the flow of refrigerant between the condenser and evaporator. The valve assembly includes i) a plunger retainer threadably received in the condenser passage, ii) a plunger moveably connected to the plunger retainer and having a throttling member controlling the flow through an orifice in the metering passage, and iii) a spring extending between the plunger retainer and the plunger and biasing the plunger, and hence the throttling member, toward the orifice.
