<p>PURPOSE:To make the captioned pump compact by opening a suction passage which is connected to the fluid passage of a pintle via a check valve and projecting turbine blades from a cylinder block on the periphery of the suction passage. CONSTITUTION:The projecting part 11 on the front end face 2a of a pintle 2 is projected out and suction passages 12, 13 are opened on the front end face 2a. The suction passages 12, 13 are connected to fluid passages 20, 21 via interposedly provided check valves 16, 17 respectively. Turbine blades 23 are projected on the rotating cylinder part 22 of a cylinder block 4. Thereby, the turbine blades 23 form a centrifugal turbine type boost pump while effecting a pumping function by the rotation of the pintle 2. Hence, the captioned pump can be made compact.</p> |
