Abstract
A master cylinder (10, 210, 310, 410) includes a housing bore (14) having at one end (16) a bearing member (18) attached thereto and retaining a sleeve member (20) within the bore (14). One piston (30, 230, 530) has at one end (32, 232) thereof a fast fill mechanism (150, 350, 450). The fast fill mechanism (150, 350, 450) includes a seal support (130, 330, 430), fast fill seal (160, 360, 460), a ramp (132, 332, 432) on the fast fill seal support (130, 330, 430), and a ramp (125, 325, 425, 525) at the one end (32, 232) of the piston. The ramp (125, 325, 425, 525) at the one end (32, 232) of the one piston (30, 230, 530) may be disposed within the piston (230, 530, 441) or on a flange support (120) mounted on the one piston (30). Displacement of the one piston (30) causes an increase in fluid pressure in an associated pressure chamber (88), the pressure causing the ramps (132, 332, 432; 125, 325, 425, 525) to resiliently engage one another until one ramp (125, 332, 432) is displaced radially and permits the fast fill mechanism (150, 350, 450) to be displaced axially along the piston (30, 230, 530, 441). The fast fill seal (160, 360, 460) disengages sealingly from the one end (32, 232) of the piston (30, 230, 530, 441) when displacement aligns the seal (160, 360, 460) with a longitudinal groove (31, 231, 331, 431) in the one end (32, 232) of the piston (30, 230, 530, 441).
