IPC: F16T1/22
Filed: 1992-11-13
Abstract: PURPOSE:To simplify a structure by providing a pressure responding member for driving a float valve to an opening position based on a deviation between the pressure of a condensing water reservoir chamber and the outside air pressure, in a trap provided with the float valve for opening/closing a valve hole in response to a water level of the condensing water reservoir chamber. CONSTITUTION:A valve seat member 8 of opening a valve hole 7 is arranged in the lower part sideward of a main unit 1 of a trap, and a condensing water reservoir chamber 4 communicates with a side of an outlet 6 through the valve hole 7. The valve hole 7 is opened/closed by a float valve 9 floated and sunk in accordance with a water level in the condensing water reservoir chamber 14. A piston 10, serving as a pressure responding member, is slidably fitted to a bottom part of the main unit 1, and this piston 10 is displaced in accordance with a differential pressure between the pressure of the condensing water reservoir chamber 4 and the atmospheric air pressure through an opening 11. In the case that the pressure in the chamber 4 is a negative pressure of the atmospheric air pressure or less, the float valve 9 is lifted by the rising displaced piston 10 through an operating member 13 so as to force the valve hole 7 opened. In this way, a constitution is simplified by eliminating necessity for a conventional bypass circuit.
