Problems solved by technology
[0004] The increasing complexity of such systems always faces issues regarding the cost of components, installation, packaging and system stability of control related components
[0005] For example, providing actuators for auxiliary water pumps and water valves for valve adjustment in branch conduit networks, accompanied by power supply and control signal transmission between decentralized actuators or pump motors, central control unit and batteries corresponding installation of the wiring and is susceptible to interference from
Additionally, due to the number and independence of components, a drive failure or cable defect could affect other areas of coolant circulation that do not comply with the unified fail-safe model used to prevent subsequent damage

Embodiment Construction
[0038] figure 1 A longitudinal sectional view of the pump is shown without showing the complete outer contour of the pump housing 1 . The pump shaft 3 extends from the pulley 4 through bearings into the pump chamber 10 of the pump housing 1 and drives the pump impeller 2 . The pump impeller 2 and pump chamber 10 (not fully shown) are structurally configured as a radial pump assembly, with a pump inlet 13 (not shown) enabling axial flow against the pump impeller 2, and wherein for connection to The first pump outlet 11 of the main delivery circuit of the internal combustion engine discharges tangentially from the pump chamber 10 via the outer spiral housing part.
[0039] The pump assembly of the coolant pump has a hydraulically adjustable regulating valve 8 known from so-called ECF type pumps. The effective flow radial area around the pump impeller 2 can be variably covered by the adjustment slide 8 by a cylindrical part coaxial with the pump shaft 3 formed to be displaced ...

The invention relates to a mechanically driven coolant pump with a controllable delivery rate for a main delivery circuit originating from a first outlet of the coolant pump and for a second A secondary delivery circuit for the outlet of the coolant pump comprising, inter alia, a hydraulic control circuit (5) derived from the coolant pump and having an input-side auxiliary pump (6), an output-side proportional valve (7) and Adjusting slide (8) as a hydraulic actuator for limiting the flow of the main delivery circuit, wherein the cylindrical part of the adjusting slide (8) is axially displaceable in the pump chamber (10) position, to shield the pump impeller (2) radially against restoring forces, in particular by means of the pressure in said hydraulic control circuit (5). Said coolant pump is characterized in particular in that a regulating valve (9) is connected to said hydraulic control circuit (5) as a hydraulic actuator in order to limit the flow of said secondary delivery circuit, wherein said regulating slide (8 ) and the actuation of the regulating valve (9) are associated with pressure ranges in the hydraulic control circuit (5).
Description
technical field [0001] The invention relates to a mechanically driven coolant pump with a controllable delivery rate for a main delivery circuit originating from a first outlet of the coolant pump and for a second Secondary conveying circuit for outlet. Background technique [0002] Due to the increased demands related to fuel efficiency and emissions of internal combustion engines, auxiliary devices such as exhaust gas recirculation systems, turbochargers, intercoolers, etc., as well as so-called split cooling, i.e. The cylinder block and cylinder head are cooled separately. Taking into account the corresponding thermal requirements in order to protect the relevant components or maintain the functionality of the heat exchanger challenges the flexibility of modern thermal management systems. [0003] In order to provide greater freedom when designing thermal management, especially with regard to specific branches and circulations, systems comprising one or more auxiliary w...
