ABSTRACT:
An improved fluid transformer which is capable of controlling the position of the operating pistons within the apparatus so that pressure equilibrium is maintained and the movements of the pistons are limited to predetermined locations within the cylinders. The transformer is capable of operating in a contaminated environment by purging unwanted fluid contamination from the internal workings of the transformer. Dynamic piston and cylinder seals are positioned such that destructive pressure forces are counteracted by opposite frictional forces during operation, thereby allowing the seals to remain effective at high pressures for long periods of time.
