摘要：A hydraulic cylinder has a piston (13) with a al (21) in aled sliding contact within a bore (12) to define a working chamber (16) ahead of the piston for the discharge of pressurid fluid from the bore via an outlet (17) when the piston is undertaking a working stroke, an inlet (20) is provided into the bore from an associated rervoir to allow connection between the rervoir and the working chamber when the piston is in a fully retracted state for recuperation of fluid from the rervoir to the working chamber. The connection between the rervoir and working chamber is provided via a sleeve (27) in the bore (12) which includes axially extending grooves (28), the grooves being clod by the piston al (21) during a working stroke of the cylinder but the ends (30) of the grooves being open when the piston (13) is in a fully retracted condition within the sleeve thus by-passing the piston sleeve to connect the working chamber and rervoir. The sleeve (27) may also have a condary function of providing an abutment (31) for a return spring (32) which returns the piston to its fully retracted position when an operating pedal (14) associated with the piston (13) is relead.
