Publication number: 20170175725Abstract: Provided is a variable-capacity compressor control valve where a decrease in the sealability or the operability due to shaft misalignment can be effectively suppressed without requiring high dimensional accuracy. The dimensions and the shape of each part are designed such that when the sub valve element closes the in-valve release passage, the tapered portion (sub valve element portion) provided at the lower end portion of the sub valve element enters the release through-hole of the in-valve release passage, and the sub valve element is thus aligned with the main valve element by the tapered portion.Type: ApplicationFiled: December 8, 2016Publication date: June 22, 2017Applicant: Fujikoki CorporationInventors: Yoshiyuki Kume, Hisashi Asano, Masaki Tomaru, Masaharu Itoh

Publication number: 20170175726Abstract: Provided is a variable-capacity compressor control valve where the size of a plunger can be reduced, the machining and assembly process can be simplified, weight reduction can be achieved, and cost reduction can also be achieved, for example. The plunger has a slit through which a valve element is assembled to the plunger by being inserted from a lateral side. The slit serves as a flow path for releasing the pressure Pc in the crank chamber to the suction chamber of the compressor from the Ps inlet/outlet port when the sub valve element has opened the in-valve release passage.Type: ApplicationFiled: December 9, 2016Publication date: June 22, 2017Applicant: Fujikoki CorporationInventors: Yoshiyuki Kume, Hisashi Asano, Masaki Tomaru, Masaharu Itoh
