Abstract
The fluid discharge device includes an axial drive device for giving an axial relative displacement to between a piston and a cylinder, a device for giving rotary motion, and a device for pressure feed of fluid. The ON/OFF control of discharge flow rate can be fulfilled by changing the fluid resistance of the discharge passage with the axial drive device.
