Method for increasing pressure in working cylinder has a smaller inner piston to further compress the fluid and achieve a working pressure greater than the pump pressure

摘要

A method for increasing the working pressure in a working cylinder system has a concentric cylinder design and with the cylinder extended by applying pressure from a pump. Additional pressure is generated under the working piston (5) by a concentric smaller piston (16) which effectively reduces the volume under the working piston and thereby increases the effective pressure of the cylinder system. The smaller piston is supplied with fluid at the same pressure as the main piston. The design can be applied to cylinders operating with various fluids such as; hydraulic, hydraulic emulsion, pneumatic, plasma etc.
