Coolant conveying unit i.e. coolant pump, for use in passenger car, has step-less regulating body that exhibits complete locking function, and arranged in flow path in flow direction behind axial pump wheel

摘要

The unit (100) has housing (102) that defines a flow path (108) of a coolant. An axial pump wheel (114) is supported in the housing. A step-less regulating body (122) that exhibits a complete locking function is arranged in the flow path in a flow direction behind the axial pump wheel. The regulating body is designed as a spherical valve (124), disk valve, slider and rotary disk valve. The flow path defines a curve in the housing in the area of the regulating body. The regulating body is arranged in a distanced manner from the wheel. The housing has tubular parts that are welded together.
