  • Patent number: 6264445
    Abstract: A scroll machine has a fluid path which is defined by two components of the scroll machine. The fluid path extends between a discharge pressure zone and a suction pressure zone of the scroll machine. The scroll machine further includes a biasing member which biases one of the two components away from the other of the two components to open the fluid path when the scroll machine is not operating. The effect of the biasing member is overcome by several revolutions of the scroll machine by centrifugal force in one embodiment and fluid pressure in another embodiment.

  • Patent number: 5803716
    Abstract: A scroll machine has an intermediate pressure cavity which is operable to open and close a leakage path between the discharge zone and the suction zone of the scroll machine. The leakage path is closed when intermediate pressurized fluid is supplied to the cavity and the leakage path is open when the cavity is open to the suction zone of the compressor. A valve (102) which can be mechanical or electrical is used to open and close a passageway extending between the cavity and the suction zone of the machine. A high pressure relief valve is incorporated into the design of the compressor to prevent slugging. The high pressure relief valve will release the intermediate pressurized fluid to suction and/or discharge when the pressure within the intermediate pressure cavity exceeds a predetermined value.

  • Patent number: 5580230
    Abstract: A scroll type machine is disclosed which incorporates an improved mounting arrangement for the non-orbiting scroll member which mounting arrangement greatly facilitates manufacturing and assembly, effectively prevents radial displacement of the non-orbiting scroll member, and offers the advantages of axial compliance. In one embodiment, the non-orbiting scroll is axially movably secured to a bearing housing by means of a plurality of bolts or bolts and sleeves. In another embodiment a rigid annular ring serves to axially movably secure the non-orbiting scroll to the bearing housing while in a third embodiment a stamped ring is secured to both the non-orbiting scroll and the bearing housing. In another embodiment a two piece main bearing housing includes an integral ring for radially positioning the non-orbiting scroll member and means for securing anti-rotation and axial stop means thereto.

  • Patent number: 5580229
    Abstract: The disclosure describes a scroll compressor which incorporates a spring biased floating seal to facilitate the start-up for the compressor. The spring biased floating seal opens a discharge to suction leakage path before and during start-up for the compressor. After a few revolutions of the scrolls of the compressor the floating seal is biased against the load of the spring to close the leakage path due to pressurized working fluid of the compressor working against the biasing of the springs.

  • Patent number: 5545019
    Abstract: Disclosed are several embodiments of a stopping device operable between the drive shaft and/or orbiting scroll of a scroll compressor and a fixed wall forming part of the compressor, for the purposes of automatically engaging the wall upon reverse operation of the compressor to thereby quickly stop such reverse operation. Damage to the compressor in the event of powered reverse is also prevented, either by permitting the machine to run free or by quickly stopping it. Also disclosed are several ways to facilitate start-up with weak motors.

  • Patent number: 5538408
    Abstract: A scroll-type machine has a motion controlling member for preventing relative rotation between a first and a second scroll member while allowing relative orbiting motion therebetween. The scroll-type machine includes a novel arrangement of a spring or other flexible member for biasing the motion controlling member in a specific direction. The biasing of the motion controlling member operates to reduce the mechanical impact noise or rattle which is caused by the vibration of the machine's operating components.

  • Patent number: 5411384
    Abstract: A scroll type machine is disclosed which is designed to enable it to be fully assembled prior to being installed in a hermetic shell and incorporates an improved mounting arrangement for the non-orbiting scroll member. This design enables the compressor to be tested without the need to first install it in the outer shell. This feature in combination with the mounting arrangement greatly facilitates manufacturing, assembly, testing, effectively prevents radial displacement of the non-orbiting scroll member, and offers the advantages of axial compliance. In one embodiment, the non-orbiting scroll is axially movably secured to a bearing housing by means of a plurality of bolts or bolts and sleeves. In another embodiment a rigid annular ring serves to axially movably secure the non-orbiting scroll to the bearing housing while in a third embodiment a stamped ring is secured to both the non-orbiting scroll and the bearing housing.

  • Patent number: 5342185
    Abstract: A scroll machine has a shell and a muffler plate which defines a muffler chamber and a main chamber. The muffler plate has a face for engaging a seal which is disposed at an interface between the muffler chamber and the main chamber. The muffler plate has a structurally advantageous configuration incorporating a frusto-conical portion and a tubular portion, which reduces distortion of the face and thereby reduces leakage between the muffler and main chambers.

  • Patent number: 4764646
    Abstract: In a distributor cap for internal combustion engines, a multi-positionable contact which can be manually rotated to successively present each of a plurality of contact surfaces to the distributor arm after an adjacent contact surface has become pitted, corroded or otherwise worn; thus increasing the useful life of the distributor cap. The contact surfaces are symmetrically arranged about the axis of rotation of the contact. Rotation can be achieved by means of a screwdriver blade introduced through the sparkplug wire terminal to act on a slotted head of the rotating contact exposed at the bottom of the sparkplug wire terminal, or by grasping the contact from underneath.
