PUMP PRESSURE MULTIPLIER

摘要

A device (10) for elevating a pressure acting on a liquid including a liquid pressure elevating mechanism (11) for receiving liquid under a first positive pressure and at a selected volume of liquid per unit of time flow rate from a liquid source (17) at an inlet port and supplying the liquid under a second positive pressure substantially greater than the first pressure and at the selected volume of liquid per unit of time flow rate to an outlet port and a liquid utilizing load connected thereto. The second pressure is sufficiently high enough to cause the liquid to become substantially compressed to thereby result in the second pressure to want to vary during intervals of time that the liquid is being compressed. A control device (12) is provided for accommodating the compressibility of the liquid so as to maintain a substantially constant second pressure.
