摘要： A thermal isolation arrangement for use in a co-rotating scroll refrigerant compressor includes various thermal insulation elements adapted to minimize heat transfer between hot rotating members of the scroll fluid device and the return refrigerant to be compressed, and between hot lubricant in the compressor and the return refrigerant. The thermal isolation elements of the present invention may be used individually or collectively to minimize the preheating of the inlet refrigerant so as to maintain the density of the return refrigerant being compressed to thereby increase the total efficiency of the scroll fluid device.

摘要： 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.

摘要： A tip seal supporting structure for use in a scroll fluid device includes intermeshing involute scroll elements mounted for relative orbital movement. Each of the scroll elements includes an involute spiral wrap which is secured to a respective wrap support plate at one axial end thereof. Each involute spiral wrap is provided with a tip seal in the other axial end thereof which engages with the wrap support plate of the other scroll element. One of the wrap support plates includes a substantially, centrally located fluid passage into which the innermost end of the involute spiral wrap of the other scroll element extends during a predetermined portion of the relative orbital movement between the scroll elements. In one embodiment of the invention, a tip seal supporting structure in the form of a bridge extends across a predetermined portion of this central fluid passage and functions to axially support the innermost portion of the tip seal that extends into this fluid passage during relative orbital movement of the scroll wraps to thereby prevent destructive vibrational effects, to permit the tip seals to extend into the center of the involute scrolls as much as possible, and to maximize the efficiency of the scroll fluid device. In other embodiments, the tip seal is attached to the involute spiral wrap by a fastener. In an additional embodiment, the end of the tip seal is supported by a shelf member formed integral with the involute spiral wrap.

摘要： Cooling means are provided for the stationary and orbiting scroll members of scroll-type apparatus. These cooling means comprise fluid coolant channels in the end plates and in the involute wraps of the scroll members and means to circulate a fluid coolant therethrough. In the case of the stationary scroll member the coolant may be water, oil or the like; while in the case of the orbiting scroll member the coolant is the lubricating oil used to lubricate a thrust bearing and the coupling means. The resulting effective cooling of the scroll members makes it possible to form scroll apparatus in large sizes.

摘要： 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.

摘要： 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.

摘要： 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.
