Document Type and Number:
WIPO Patent Application WO/2012/095766
Kind Code:
A9
Abstract:
A differential master cylinder includes a hollow primary piston (12) and a hollow secondary piston (13) with different diameters, which are open at least at one end and are mutually associated in telescopic manner so that the primary piston (12) slides on the secondary piston (13), which is stationary, and so that the pistons (12, 13) define, with the internal surface of a bore (11) housing both pistons, at least one external annular chamber (16) connected to a user device. The invention also relates to a method of driving a user device with pressurised fluid by means of the cylinder and to a balancing device for a set of master cylinders.
