BIASED SEAL ASSEMBLY FOR HIGH PRESSURE FLUID PUMP |
摘要 |
A method and apparatus for biasing a seal assembly in a high pressure fluid pump. In one embodiment, the fluid pump includes a reciprocating plunger, a seal carrier disposed about the plunger, and a seal supported by the seal carrier and sealably engaged with the plunger. The seal may be biased toward the seal carrier with a spring and may include a flange that engages the spring to restrict lateral motion of a spring relative to the reciprocating plunger. The flange may engage an inner and/or an outer surface of the spring. Where the spring is a coil spring, the flange may be continuous around the circumference of the spring or may include a plurality of spaced apart projections located around the circumference of the spring.
