  • Publication number: 20080169647
    Abstract: A pipe coupling assembly includes two identical pipes each extending into an enlarged collar and then into a hemispherical socket each with a socket radius. A bulbous insert engages the sockets of the pipes. A clamping mechanism is disposed about the pipes and includes two blocks for holding the sockets into engagement with the insert. The insert has two necks both extending axially around the flow passage and fitting into the pipes. The insert defines a slot extending radially and circumferentially about the axis for allowing movement of two hemispheres relative to one another. Each of the hemispheres has an insert radius. The socket radii are greater than the respective insert radii for establishing a contact line between the insert and the sockets which becomes a contact band as the blocks move together.

  • Patent number: 7178450
    Abstract: A compressor includes a housing and a drive shaft extending along a longitudinal axis and rotatably supported by the housing. A pocket is defined in the drive shaft and extends to a bottom portion having a diameter smaller than a diameter of the pocket. A pair of sealing lip portions disposed between the housing circumscribing the drive shaft. A pair of channels is defined in the drive shaft with one of the channels exposed between the spaced lip portions to deliver a lubricant therebetween under pressure.

  • Patent number: 7093451
    Abstract: A blowoff valve assembly includes a diaphragm separating a refrigerant connection from an ambient port open to the atmosphere. The refrigerant connection is preferably connected to air conditioning system such that the diaphragm is in contact with refrigerant from the system. The diaphragm is deflectable based on the pressure of the refrigerant and is operatively connected to a switch. When pressure of the refrigerant drops to a predetermined level, the diaphragm deflects to activate the switch. Additionally, the assembly also includes a detonable squib that explodes and ruptures the diaphragm, allowing the refrigerant to flow from the refrigerant connection to the atmosphere. Additional features, such as sensors for detecting refrigerant outside of the system, a collision subsystem, and an associated controller are also disclosed.

  • Patent number: 6968706
    Abstract: Each blow-off valve includes a valve body with a first movable wall defining a portion of the liquid fluid passage therein and a second movable wall defining a portion of the suction fluid passage therein. An actuator interconnects the movable walls for simultaneously moving the walls and opening the fluid passages in response to the electrical leakage-warning signal. In the species of FIGS. 2 and 3, the movable walls are integrally united with the valve body and include frangible sections that are fractured by an explosive squib to separate the movable walls from the body to simultaneously open the liquid and suction fluid passages. In the species of FIG. 5, the movable walls are separate valve elements disposed in a circular bore that opens the passages to the ambient surroundings. The actuator includes a spring, for biasing each of the valve elements out of its respective bore, and a holding device that weakens in response to the electrical leakage-warning signal.
