Abstract
A clutch hydraulic slave cylinder comprising a cylinder body, a primary piston sealingly reciprocable relative to the body and co-operating with the body to form a first fluid chamber within said body, and a secondary piston sealingly reciprocable relative to the primary piston and co-operating with the primary piston to form a second fluid chamber. the second fluid chamber is connected to the first fluid chamber through a valve means. The primary piston is biased by a spring means from a fully retracted condition to an at-rest condition in which it can exert a pre-load on a clutch bearing, and said valve means is open when the primary piston is in the fully retracted condition, and is closed when the primary piston is in the at-rest condition.
Claims16
A clutch hydraulic slave cylinder (16) comprising a cylinder body (14), a primary piston (41) sealingly reciprocable relative to the body and cooperating with the body to form a first fluid chamber (60) within said body, and a secondary piston (70) sealingly reciprocable relative to the primary piston and co operating with the primary piston to form a second fluid chamber (80), the second fluid chamber being connected to the first fluid chamber through a valve means (82) characterised in that the primary piston (41) is biased by spring means (54) from a fully retracted condition to an "at-rest" condition in which it can exert a pre load on a clutch bearing, and said valve means (82) is open when the primary piston is in the fully retracted condition and is closed when the primary piston is in the "at-rest" condition.
