Coolant pump of impeller for internal combustion engine, has intake passage having flow guide which forms rotationally-prone vortex of sucked fluid, whose rotation axis is parallel to rotational axis of impeller

摘要

The coolant pump (1) has pressure chamber (10) in pressure side (9), and suction chamber (3) in suction side (4) with an intake passage (5). The intake passage has a flow guide (13) which forms rotationally-prone vortex of the sucked fluid, whose rotation axis is parallel to the rotational axis (7) of the impeller.
