WIPO Patent Application WO/2022/158238
Kind Code:
A1
Abstract:
[Problem] To provide an electrically driven valve that can effectively suppress the collision noise of a plunger without a change in performance. [Solution] A solenoid valve 1 wherein a cushioning member 50 made of an elastically deformable synthetic resin is disposed in an internal space 33b of a plunger 33. When the plunger 33 is separated from an upper end wall part 32b of a case 32, the upper end 50a of the cushioning member 50 protrudes from the internal space 33b toward the upper end wall part 32b. When the plunger 33 moves toward the upper end wall part 32b, the upper end 50a of the cushioning member 50 contacts the upper end wall part 32b and is pushed into the internal space 33b, and the plunger 33 contacts the upper end wall part 32b.
