Title:
HIGH PRESSURE PUMP
Document Type and Number:
Japanese Patent JPH07180671
Kind Code:
A
Abstract:

PURPOSE: To convert the energy of a specific pressure fluid effectively into mechanical energy so as to heighten the pressure of the fluid by disposing three kinds of port means in specific positions in a displacment type pump formed by accommodating a rotor with vanes in a casing.

CONSTITUTION: A rotor 2 is formed by inserting vanes 3 (3A...), energized outward respectively by springs, into a grooves divided almost circumferentially in four equal parts, and this rotor 2 is rotatably accommodated in a casing 1. The casing 1 has a first port 10 connected to the fluid source of first pressure P1, and the rotor 2 is rotated by a fluid filled in a closed chamber 14 partitioned between the vanes 3, 3. At this time, a second fluid escapes from a second port means 5 in the state of the vane 3B passing the rear edge 5C of the second port 5. When the pressure of the closed chamber 14D rises to exceed the valve opening pressure of a check valve 8, a valve body 8A opens to deliver the fluid of third pressure P3 (>P1) from a third port 6.
