Abstract
Official abstract text for this publication.
A mechanical coolant pump for an internal combustion engine includes a pump rotor wheel comprising a blocking ring and rotor blades. The rotor blades are configured to pump a coolant radially outwardly. Variable pump stator blades are pivotably supported by a static blade holding ring at a first axial blade end. The variable pump stator blades are arranged radially outwardly of the pump rotor wheel. The blocking ring is arranged to partially overlap a second axial blade end.
First claim
Opening claim text (preview).
What is claimed is: 1. A mechanical coolant pump for an internal combustion engine, the mechanical coolant pump comprising: a pump rotor wheel comprising a blocking ring and rotor blades, the rotor blades being configured to pump a coolant radially outwardly; variable pump stator blades pivotably supported by a static blade holding ring at a first axial blade end, the variable pump stator blades being arranged radially outwardly of the pump rotor wheel; and a second axial blade end, wherein the blocking ring is arranged to partially overlap the second axial blade end, the variable pump stator blades include a pivot axis, and the static blade holding ring includes axial pivot openings which are configured to receive the pivot axis of the variable pump stator blades, the second axial blade end includes a flat stop face, and the blocking ring is configured to overlap the pivot axis of the variable pump stator blades. 2. The mechanical coolant pump as recited in claim 1 , further comprising a main pump body, wherein the static blade holding ring is mounted as a separate part at the main pump body. 3. The mechanical coolant pump as recited in claim 1 , wherein the flat stop face and the blocking ring are arranged to form a gap between the flat stop face and the blocking ring. 4. The mechanical coolant pump as recited in claim 3 , wherein a height of the gap is between 0.5 and 5 mm. 5. The mechanical coolant pump as recited in claim 3 , wherein a height of the gap is less than a length of the pivot axis of the variable pump stator blades. 6. The mechanical coolant pump as recited in claim 1 , wherein the blocking ring is an integrated part of the pump rotor wheel. 7. The mechanical coolant pump as recited in claim 1 , wherein the blocking ring is formed as a separate part of the pump rotor wheel.
