<p>PURPOSE:To secure a small-sized hydraulic pump of practical use, by making a hydraulic fluid for driving plural devices so as to be fed to the pump with a radial plunger pump utilized. CONSTITUTION:Externals of a pump is made up of a pump housing 1 and a side housing 2. Inside these housing 1 and 2, a rotor 3 having plural cylinder holes 31 as for 6 pieces is set up so as to rotate therein. And, at each cylinder 31, there is provided with each of interconnecting passages formed in a cylindrical part 3c of the rotor 3. This interconnecting passage consists of an interconnecting passage 34a to be connected to a first discharge port 14a and an interconnecting passage 34b to be connected to a second discharge port 14b. And, these passages 34a and 34b are alternately set up. With rotation of the rotor 3, a piston 4 gets operating and oil is fed out of a suction port 13 whereby the oil is made so as to be alternately dischargeable to both discharge ports 14a and 14b.</p> |
