A shock absorber (2) includes a piston assembly (6) and a damping fluid
cylinder (4) having a first end (22) and defining a damping fluid chamber
(56). The piston assembly includes a piston (14) mounted to a shaft (8).
The piston divides the damping fluid chamber into first and second
variable-volume parts (58, 60). At least one restricted flow path is
provided between the variable-volume parts of the cylinder, preferably one
(18) for compression and one (19) for rebound or extension. A sealing ice
scraper assembly (30) is mounted to the first end of the cylinder. The
scraper assembly includes a sealing ice scraper sleeve (34) having a
generally cylindrical scraper surface (36). A gap of a desired size,
typically quite small, is provided between the scraper surface and the
shaft. A recess (38) is formed into the scraper surface and houses an
outer fluid seal (40) therein. Therefore, ice (66) and any liquid within
the gap, which may have been produced in part by the interaction of the
scraper sleeve, shaft and ice, are at least inhibited, if not prevented,
from passing the outer fluid seal and into the damping fluid chamber.
