Abstract

The non-return valve is for machines using water, partic. dishwashers, having a tubular housing accommodating a sealing ring in an annular groove. The valve body moves in the lengthwise direction of the housing. The sealing ring (18) is a clearance fit in the groove (17), both in the radial and the axial direction. it can be of roughly square section (19), with concave sides (20) and radiused corners (21). The design avoids distortion of the ring, so that it continues to give a good seal even under low pressure.
