IPC: F16K5/00
Filed: 1999-07-02
Abstract: PURPOSE: A drain cock is provided to drain water and impurities out of an air tank according to the pressure change of the air tank as a brake pedal works. CONSTITUTION: When water and impurities is filled in a first chamber(5), high pressure air is supplied to the brake valve from an air tank(51) and the pressure in the air tank becomes low if a driver operates a brake valve. The pressure in the first chamber communicated with the tank is decreased and the pressure in the a second chamber(6) is relatively increased. Thus, the second chamber pressure is higher than the first chamber after the high pressure air is discharged. A diaphragm(10) is pressurized and the central portion is bent toward the first chamber when the second chamber has a higher pressure than the first chamber. A blocking portion(9) is separated from a discharge hole(3) and the impurities as well as the water in the second chamber is drained out through the discharge hole. The impurities and the water is drained very fast by the high pressure of the second chamber.
