Problems solved by technology

The placement of this pivoting cover within the lubricant outlet passage restricts coolant flow even in the open position of the cover and causes flow resistance
In addition, such pivot covers can become seized due to wear, deformation, and particles in the lubricant adhering to the cover and in the recesses of the cover

Embodiment Construction

[0022] exist figure 1 In , a mechanical coolant pump 10 for an internal combustion engine is shown. The mechanical coolant pump 10 comprises a main pump body 11 whereby the main pump body is mounted directly to the engine block via a flange 12 or may have a cover plate (not shown).

[0023] The main pump body 11 houses a rotatable impeller 18 which sucks in coolant axially and pumps the coolant radially outward into a volute 15 . The impeller 18 is driven by the combustion engine using a drive belt (not shown) which drives a drive wheel 38 of the mechanical coolant pump 10 . The coolant flows from the volute 15 into the outlet channel 16 due to centrifugal force and passes through the outlet valve 20 to the outlet opening 14 . An outlet valve 20 is located at the end of the outlet channel 16 .

[0024] The outlet valve 20 comprises a movable flat valve plate 22 which is movable within the cross-section of the outlet channel 16 through a passing slit 24 in an outlet channel ...

Abstract

The present invention refers to a mechanical coolant pump 10 for an internal combustion engine. The mechanical coolant pump 10 for an internal combustion engine comprises an impeller 18 for pumping the coolant into an outlet channel 16 which comprises an outlet valve 20. The outlet valve 20 comprises a shiftable flat valve plate 22 which is shiftable in a transversal plane of the outlet channel 16 through a passing slit 24 in the outlet channel wall 26.

Description

technical field [0001] The invention relates to a mechanical coolant pump for an internal combustion engine with an impeller for pumping coolant into an outlet channel, wherein the outlet channel includes an outlet valve. Background technique [0002] A mechanical coolant pump is a coolant pump driven by a combustion engine, for example by using a drive belt to drive the drive wheels of the pump. As long as the combustion engine is cool, only minimal coolant flow is required. Therefore, a mechanical coolant pump provided with an outlet valve for controlling the coolant circulation flow is used. As long as the combustion engine is cool, the outlet valve is closed, minimizing circulation of the lubricant, thereby reducing the combustion engine warm-up time. [0003] Typically, the outlet valve takes the form of a pivoting flap whereby the pivoting flap is located in the lubricant outlet passage. The pivotal cover can be controlled to rotate the cover to an open or closed po...
