Document Type and Number:
Japanese Patent JP2000505522
Kind Code:
A
Abstract:
An impeller pump with thermostatically adjustable guide vanes is suitable for use as an automotive coolant pump. The pump is driven by a constant speed electric motor, and flow variation is controlled by varying the orientation of the vanes. Orientation of the vanes is effected by a wax-type thermostat, which senses coolant temperature: flow is increased when the coolant is hot, and decreased as the coolant cools. The variable guide vanes are mounted for pivoting about radial axes, and are located just upstream from the pump impeller.
