An expander driven compressor assembly is disclosed comprising a scroll-type expander having at least one pair of meshed axially extending involute spiral wraps wherein one of the wraps orbits relative to the other wrap and a scroll-type compressor having at least one pair of relatively orbiting meshed axially extending involute spiral wraps. The orbital wrap of the expander is drivingly connected to the orbital wrap of the compressor through a common synchronizer and counterweight assembly. Auxiliary drive power developed by the expander and not required to drive the compressor is used to drive a power take-off shaft. In addition, expansion struts are proved to compensate for thermal expansion or contraction of the relatively orbiting scroll wraps. By this arrangement, a compact and efficient expander driven compressor assembly is achieved.

A scroll fluid device is provided with a synchronizer arrangement that prevents relative rotation between the involute scroll wraps defining fluid working chambers while permitting the wraps to orbit relative to each other to perform work on fluid moved through the device or to expend work through the reaction of fluid moving through the device. The synchronizer comprises axially extending teeth affixed to one of the scroll support end plates interdigited with grooves affixed to the other end plate. The grooves of the synchronizer each have a width that accommodates the orbital excursion of each tooth extending into the groove such that, during orbital movement of one scroll wrap relative to the other, the teeth engage the side walls of the groove to prevent rotation of the scroll wraps relative to each other in either direction. The synchronizer also permits movement of one scroll wrap relative to the other along a line generally extending between the involute centers of the wraps in a direction that reduces the orbit radius.

Method for forming scroll members comprising an end plate having an involute wrap rigidly affixed thereto. The end plate and involute wrap are precision formed, e.g., by casting, either as an integral element or as two separate elements and then the scroll member is broached to the desired dimensional accuracy and finish. Push broaching is accomplished with an involute broaching tool which has a single terminating cutting edge on one or both sides of an involute blade cutter.

A two-piece scroll member, for use in scroll apparatus, is fabricated by seating a separately formed involute wrap in an involute channel cut in the end plate. The channel has at least one reentrant groove and the surface of the wrap is configured to engage the groove. Locking means are coined into the groove to rigidly affix the wrap to the end plate.

A thrust bearing/coupling component for use in scroll-type apparatus which may be a compressor, expander, fluid pump or vacuum pump. The resulting apparatus is particularly suited for use as auxiliary equipment in automotive power systems. The component of this invention comprises rotating or oscillating load carrying members, preferably ball bearings, confined within facing indentations cut in the orbiting scroll member end plate surface and an associated surface in a member stationary with respect to the orbiting scroll member. The thrust bearing/coupling component couples the stationary and orbiting scroll members in a predetermined angular relationship and it may be used to carry either expansive or compressive axial loads on the scroll members to achieve efficient radial sealing of the moving scroll fluid pockets while controlling surface wearing so that the scroll apparatus may be operated for an extended period of time without servicing.

A scroll member is provided for use in scroll-type apparatus. It is formed of a separate end plate having an involutely configured groove in the face thereof and a separate involute wrap which is seated in the groove. The seating of the wrap in the groove may be such as to permit it to undergo small axial and radial excursions within the groove to impart compliance/sealing characteristics to the scroll member. Alternatively, the wrap may be rigidly mounted in the groove and, if desired, separate compliance/sealing means provided for the wrap. The construction of scroll members according to this invention achieves a marked decrease in cost of the scroll members and of scroll-type apparatus incorporating them.

A bearing and lubrication system for a sealed, integrated motor driven co-rotating scroll refrigerant compressor includes hydrostatic bearings and an independent motor driven lubricant supply pump for supplying lubricant to the hydrostatic bearings mounting in the housing. The housing is divided into a high-pressure section that receives compressed refrigerant and a low pressure section containing the involute scroll compressor wraps. Individual lubricant supply sumps are provided in the high and lower pressure housing sections for supplying lubricant to the compressor bearings. The lubricant pump is capable of drawing lubricant from one or both of the lubricant supply sumps. A lubricant level sensor associated with one of the low or high pressure housing sumps is provided to maintain a desired level of lubricant therein. The lubricant supply pump is controlled so that pressure is supplied to the hydrostatic bearings during compressor operation. The lubricant may be pressurized by compressed refrigerant in the high-pressure housing section for supply to the compressor bearings with or without operation of the lubricant supply pump.
