Patent ID: 7546999

Claim:
A solenoid valve for controlling water supply, comprising: a constant flow control member having a chamber at one side of a connecting pipe branched from a body which has an outlet port, the chamber temporarily accommodating water and quantitatively supplying the water by using a flow control sheet; and a low-pressure flow control member installed in an inlet port, such that an outer periphery of the low-pressure flow control member is positioned adjacent to an inner sidewall of the inlet port, the low-pressure control member communicating with the connecting pipe of the chamber, the low-pressure flow control member having a hollow body to enclose the flow control sheet, wherein a first flow channel is formed between the outer periphery of the low-pressure flow control member and the inner periphery of the inlet port, and a second flow channel is formed by a hole through the low-pressure flow control member and a hole through a resilient member, the hole through the low-pressure flow control member being coaxially aligned with and in communication with a passage through the flow control sheet, wherein the hole through the low-pressure flow control member and the hole through the resilient member are coaxially aligned with each other and in communication with each other and in communication with the passage.
