Device in which theoperation pressure p1 of the primary pressure system is brought to a higher pressure p2 in the secondary system. The pressure boost factor is given by the ratio of the primary and secondary surface areas:
F1 = F2 or F1 = p1 * A1 and F2 = p2 *A2
This surface area ratio also defines at the same time the transmission ratio of the pressure amplifier.
It is possible to operate with the same pressure fluid and also with different pressure fluids (e.g. compressed air/ oil) in the two pressure systems.
