Title:
ELECTROMAGNETICALLY DRIVEN VALVE AND REFRIGERATION CYCLE SYSTEM COMPRISING SAID ELECTROMAGNETICALLY DRIVEN VALVE
Document Type and Number:
WIPO Patent Application WO/2024/004343
Kind Code:
A1
Abstract:
Provided are an electromagnetically driven valve in which adverse events can be minimized while magnetic efficiency is ensured, and a refrigeration cycle system comprising said electromagnetically driven valve. Due to a suction element (52) having a press-fitted part (522), X-direction positional displacement between the suction element (52) and a cylinder part (21) can be minimized, error in the distance between the suction element (52) and a plunger (51) can be minimized, and fluctuation of suction force can be minimized. This makes it possible to suitably open and close valve ports (32A to 32C) by using a valve body (4) and to minimize adverse events. Due to a welded part (7A) having an open part (71) that is opened to the outer-circumferential side, if a protrusion is about to be produced due to melting, the protrusion can be caused to protrude toward the outer-circumferential side (the protrusion can be released to the outer-circumferential side), and protrusion of the welded part (7A) to one X-direction side can be minimized. This makes it possible to ensure magnetic efficiency while making it less likely for a gap to form between an end surface (521) of the suction element (52) and an inner surface (551A) of an outer case (55).
