Title: solenoid valve
Inventor: SATO YUTAKA
IPC: F16K31/06
Filed: 2021-01-14
Abstract: To maintain a state in which a valve element is separated from a valve seat with smaller pressing force of a spring.SOLUTION: A valve body includes an inflow passage 222 of working fluid, an outflow passage 223, a valve seat 227 which is formed between the inflow passage and the outflow passage and to which a valve element 214 is abutted, a valve chamber 225 which is formed between the valve seat and the inflow passage, and a pressure chamber 240 which is formed between the valve seat and the outflow passage. When the valve element is separated from the valve seat, a flow velocity of the working fluid flowing into the pressure chamber from the valve chamber is increased when the working fluid flows through a gap between the valve seat and the valve element, and a pressure is decreased at a downstream side of the valve element. However, the flow of the fluid is hindered in the pressure chamber, and therefore, the pressure can be recovered. Accordingly, force for drawing the valve element to the valve seat side becomes small, and pressing force of a spring for maintaining a valve open state of the valve element can be made small, and thus, excitation force of a coil for moving a plunger and the valve element against the pressing force of the spring can be also made small.SELECTED DRAWING: Figure 2
