Pressure intensifier for discharging fluid at constant flow rate

摘要

A pressure intensifier for ejecting fluid at a constant flow rate includes a hydraulic pump, a hydraulic motor, a supply channel, a first control unit, and a second control unit. The hydraulic pump pumps an introduced fluid to eject the fluid through an ejection channel. The hydraulic motor is driven by the introduced fluid and drives the hydraulic pump to cause the fluid ejected by the hydraulic pump to be intensified. The supply channel allows the hydraulic pump and the hydraulic motor to be supplied with the fluid. The first control unit opens or closes the supply channel, and the second control unit operates the first control unit to cause the first control unit to close the supply channel if the fluid ejected through the ejection channel is larger than a predetermined pressure.

1. A pressure intensifier for ejecting fluid at a constant flow rate, comprising:
a hydraulic pump for pumping an introduced fluid to eject it through an ejection channel; a hydraulic motor driven by the introduced fluid and driving the hydraulic pump to intensify hydraulic pressure of the fluid ejected by the hydraulic pump; a supply channel for supplying the hydraulic pump and the hydraulic motor with the fluid; a first control unit for opening or closing the supply channel; and a second control unit for operating the first control unit to cause the first control unit to close the supply channel if the hydraulic pressure of the fluid ejected through the ejection channel is larger than a predetermined pressure.
