Abstract (en)
[origin: US4189160A] A sealing cup to be used for a hydraulic piston-cylinder device the cup having an outer lip with a leading edge adapted to slide along a wall when fitted in the device. The angle alpha of the leading edge with respect to the cylinder axis is made smaller than the angle of a portion other than the leading edge with respect thereto, and is made as 1 DEG </= alpha </=15 DEG in the free condition of the cup. When the sealing cup is installed to be slid in the cylinder, a wedge-shaped clearance is formed between the leading edge and the cylinder wall due to provision of the angle alpha , thereby admitting the fluid therein to decrease the slide resistance of the sealing cup.
