PRESSURE SWITCH

摘要

PURPOSE: A pressure switch is provided to improve the efficiency of the pressure switch by making one side of an L-shaped pipe a shaft and vertically installing the shaft to a hooter surface and rotating the other side of the L-shaped pipe. CONSTITUTION: A ventilating opening pipe(1) is installed at the central portion of a pressure chamber hooter(2). The ventilating opening pipe(1) is inserted into a flange portion of the hooter by interposing an oil seal so as to accomplish the water proof. A bush nut prevents the ventilating opening pipe(1) from being deviated from the hooter(2). The pipe(1) can be freely rotated about a shaft even when the hooter(2) is fixed. One side of an L-shaped pipe having a ventilating opening becomes a shaft. The shaft is vertically installed on the hooter surface by interposing a seal material to the pressure chamber hooter.
