摘要： A scroll compressor includes a capacity modulation system. The capacity modulation system has a piston that is connected to the non-orbiting scroll that disengages the non-orbiting scroll from the orbiting scroll when a pressure chamber is placed in communication with the suction chamber of the compressor. The non-orbiting scroll member moves into engagement with the orbiting scroll when the chamber is placed in communication with the discharge chamber. The engagement between the two scrolls is broken when the pressure chamber is placed in communication with fluid from the suction chamber. A solenoid valve controls the communication between the pressure chamber and the suction chamber. By operating the valve in a pulsed width modulated mode, the capacity of the compressor can be infinitely varied between zero and one hundred percent.

摘要： A scroll compressor includes a discharge valve assembly for blocking compressed refrigerant flow from the discharge chamber through the scroll members. This blocking of flow results in an increased performance for the scroll compressor by minimizing the recompression volume due to the configuration of the value assembly and thus the elimination of reverse rotation at shut down. The discharge valve assembly includes a valve seat, a disc shaped valve member, a retainer, a spring and a stop secured within a recess formed within the scroll member.

摘要： A scroll-type machine is disclosed which is particularly well suited for use as a compressor in refrigeration and air conditioning systems and incorporates a unique arrangement for modulating the capacity thereof. In one group of embodiments the capacity of the scroll-type machine is modulated by relative axial movement between the scroll members so as to form a leakage path across the wrap tips and opposed end plates. In another group of embodiments, modulation is achieved by reducing the orbital radius of one of the scroll members to thereby form a leakage path across the flank surfaces of the wraps. In the second group, a plurality of pin members are moveable from a first and second positions. In a first position the plurality of pin members operably enable the scroll members to orbit and in a second position the pin members restrict the orbiting motion of the first scroll members. Both types of scroll separation may be accomplished in a time pulsed manner to thereby enable a full range of modulation with the duration of the loading and unloading periods being selected to maximize the efficiency of the overall system. A motor control arrangement is also disclosed which may be used with either of the modulation methods mentioned above to increase the efficiency of the motor during periods of reduced load. Additionally, either of the modulation arrangements mentioned above may be combined with a delayed suction form of capacity modulation with or without the motor control feature to thereby achieve better operating efficiency under certain conditions.

摘要： A compressor (10) is provided and may include a shell (12), a main bearing housing (18) disposed within the shell (12), a driveshaft (16), a non-orbiting scroll member (24), and an orbiting scroll member (22). The driveshaft (16) may be supported by the main bearing housing (18). The non-orbiting scroll member (24) may be coupled to the main bearing housing (18) and may include a first lubricant supply path in fluid communication with a lubricant source. The orbiting scroll member (22) may be rotatably coupled to the driveshaft (16) and may be meshingly engaged with the non-orbiting scroll member (24). The orbiting scroll member (22) may include a recess (96) that is moved between a first position in fluid communication with the first lubricant supply path and a second position fluidly isolated from the first lubricant supply path.
