摘要： A resin lip type seal (1) capable of increasing safety against rupture by reducing the rigidity of a plate-like lip (4) bent about the tip point A of a roughly wedge-shaped recessed part (8) to reduce stress concentration at the point A, suppressing the lowering of sealability due to a reduction in the creep of the lip, and increasing the follow-up capability of the lip to the eccentricity of its axis. Slits are formed in the slidable contact surface (41) of the plate-like lip (4) or/and the anti-slidable contact surface (42) thereof. Slits (7) are also formed in the sloped slidable contact surface (21) of the inner lip (2) of the seal. Then, the ratio of the portion of each of the slidable contact surfaces where the slits (7) are formed is set to ½ or more of each of the surface areas of the slidable contact surfaces (21, 41, 42

摘要： A high-pressure fuel pump with seal system that is usable under the conditions of “high speed”, “high pressure” and “fuel resistance”. There is provided a high-pressure fuel pump comprising an axle capable of reciprocating motion in the pump and seal system (21) for separating/sealing of fuel and lubricating oil as sealing objects in a circular space within a housing having the axle passing therethrough, wherein the seal system (21) consists of a combination of fuel-side seal (31) for sealing of fuel and lubricating-oil-side seal (41) for sealing of lubricating oil. The fuel-side seal (31) is composed of plastic-made seal ring (32) and rubbery-elastomer-made O ring (33) for backup of the seal ring (32). The lubricating-oil-side seal (41) consists of a single body of single-lip-type oil seal (42) wherein rubbery-elastomer-made seal lip (44) fitted to metal ring (43) is arranged so as to face the lubricating oil side. The spacing between the fuel-side seal (31) and the lubricating-oil-side seal (41) is set so as to be larger than the reciprocating motion distance of the axle.
