Fluid pressure amplifier

The amplifier has a piston 38 dividing a housing into a larger area inlet cavity 36 and a smaller area outlet cavity 46, applied pressure being selectively directed to either of these chambers by a valve 32. A vent is provided to allow accumulated compressible fluids to be displaced out of the cavit...

More Information
Summary:The amplifier has a piston 38 dividing a housing into a larger area inlet cavity 36 and a smaller area outlet cavity 46, applied pressure being selectively directed to either of these chambers by a valve 32. A vent is provided to allow accumulated compressible fluids to be displaced out of the cavity 46 prior to stroking of the piston 38 which occurs as a result of pressurising the cavity 36 through movement of the valve 32. The piston has a check valve 52 allowing fluid to be displaced through it from the cavity 46 to the cavity 36 when pressure fluid is directed to the cavity 46. An intermediate cavity 58 houses a piston biassing spring 56 and is also vented 60.
