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 fluid flow control system includes a disposable cartridge which is receivable in a shifting carrier body portion of a control module. The disposable cartridge houses a disposable pump and a pressure transducer element which are fluidly interconnected by an internal fluid flow circuit formed in part by an elastomeric separating sheet within the cartridge. Following loading of the cartridge, shifting of the carrier body portion automatically results in a drive connection to the pump, the positioning of various flow control valves within the cartridge and the seating of the pressure transducer element to the control module. External flow lines are readily placed in fluid communication with the internal fluid flow circuit through exterior connection ports provided on the cartridge.

摘要： A scroll fluid device includes a synchronizer having a plurality of first synchronizer elements, fixedly secured to or integrally formed along a flank portion of one of a pair of meshed wraps, which are interdigited with a plurality of second synchronizer elements carried by a wrap support plate of the other meshed wrap. According to a preferred embodiment of the invention, the synchronizer elements carried by the wrap flank comprise teeth which extend into grooves formed in the support plate of the other wrap. In addition, the synchronizer elements on each of the wraps extend about a predetermined angular portion, preferably 180.degree., of each of the scroll elements. In this manner, it is possible to form each wrap with both tooth and groove portion,s, each portion extending about complimentary 180.degree. portions of the wrap, which are interdigited with corresponding tooth and groove portions on the other wrap. By forming the synchronizing elements with the flanks and support members of the wraps respectively, the overall dimensions of the scroll fluid device can be significantly reduced, i.e., in the range of 25%. In addition, due to the construction of the synchronizer, fluid can tangentially enter a radially outer inlet zone of the scroll device when the device is used as a compressor, for example. This arrangement further enables delivery of the fluid to the transport chamber(s) formed between the wraps at a reduced velocity in order to increase operating efficiency.

摘要： Centrifugal blowers which maintain a substantially constant (usually .+-.5%) static pressure field around the circumference of the blower's impeller, notwithstanding at least one abrupt radial or axial discontinuity in the volute of the blower, e.g., due to one or more external axial and/or radial constraints in an irregularly shaped package. The blower accommodates such constraints by including discontinuities in the volute; therefore the blower takes advantage of relatively unconstrained segments of the package to have an overall large size. Notwithstanding the volute discontinuities, a substantially constant pressure field around the impeller is achieved by maintaining a specific relationship between G(.THETA.) and H(.THETA.), G(.THETA.) being radial extent of the volute as a function of the angular displacement .THETA. around the impeller's circumference and H(.THETA.) being the axial extent of the volute as a function of .THETA., angular displacement around the volute.

摘要： An apparatus (10) for the controlled heating of fluid comprises a general elongated electrically heating core (16) with an exterior surface (36) formed of a material having a high thermal conductivity and frustoconically shaped to slidingly receive an assembly (14) so that the assembly envelops the surface along at least a portion of the length of the core. The assembly (14) forms a sealed passageway (46) for generally unidirectional sheet-like flow upward along the core (16). A control system (20) selectively operates the heating core (16) so that the fluid, under varying flow rates, is warmed to a desired temperature without overheating, before the fluid flows from the passageway (46).

摘要： An aerodynamic drag reduction arrangement for use in a mechanical device that incorporates a high speed rotating element includes a boundary layer control member that defines a control surface. The control member is positioned adjacent the rotating element so as to optimize the clearance therebetween in order to effectively block axial flow and prevent radial pumping in order to minimize power consumption. The aerodynamic drag reduction arrangement is particularly adapted for use in electric rotors and scroll fluid devices.

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.
