Open the CIPO recordAbstract From the Canadian patent
A faucet has a sealing member clamped at its periphery and overlying an orifice through which fluid is to flow. Pressure applying means maintains the sealing member in sealing engagement with the wall defining the orifice. Upon removal of the pressure applying means the sealing member moves away from the orifice to permit flow. The pressure applying means is located n a valve body which is screwed into the faucet housing and acts to change the periphery of the sealing member. The valve body may be removed by removing the handle and engaging a pair of projections within the handle with a pair of ears on the valve body. The sealing member is thus unclamped and easily removed.
