Abstract
A hydraulic master cylinder and reservoir assembly having a master cylinder body with a fluid reservoir, and a master cylinder bore with a piston assembly sealingly reciprocal within the bore. The fluid reservoir has at least a portion thereof concentric with the master cylinder bore and is sealed from the atmosphere by a rolling diaphragm, which is sealingly slidable relative to an internal surface of the reservoir allowing the volume of fluid within the reservoir to expand or contract.
Claims19
A hydraulic master cylinder and reservoir assembly (10) having a master cylinder body (11) with a fluid reservoir (12), and a master cylinder bore (18) with a piston assembly (35) sealingly reciprocal within the bore, the assembly being characterised in that the fluid reservoir (12) has at least a portion thereof concentric with the master cylinder bore (18) and being sealed from atmosphere by a rolling diaphragm (56), an inner periphery (58) of the diaphragm being sealed to the piston assembly (35), and an outer periphery (57) of the diaphragm being sealingly slidable relative to an internal surface (16) of the reservoir allowing a volume of fluid within the reservoir to expand or contract.
