摘要：
An overpressure device for applying pressure from a first hydraulic fluid to a second hydraulic fluid comprises:
a housing (20) in which is located a piston (1),
an opening (7) in the housing (20) for the entry of the first hydraulic fluid to one side of the piston (1),
a second opening (12) in the housing (20) for the entry of the second hydraulic fluid to a chamber on the other side of the piston (1) whereby the pressure of the first hydraulic fluid is exerted on the second hydraulic fluid, and
an additional means (5) of exerting pressure on the piston (1) so that pressure exerted on the second hydraulic fluid is greater than that of the first hydraulic fluid alone.
