[0019] will refer to Figure 1 to Figure 7 The first embodiment is described. The valve device 10 is applied to, for example, a cooling system 1 that circulates a coolant that cools an internal combustion engine (hereinafter referred to as an engine) 2 of a vehicle, and controls the flow rate of the coolant circulating in the cooling system 1 . The coolant in this specification is, for example, a coolant whose main component is ethylene glycol. Any other suitable type of liquid may be used as the coolant of the present disclosure.

[0020] Such as figure 1 As shown, the cooling system 1 includes a valve device 10 , an engine 2 , an air conditioner heat exchanger 3 , an oil cooler 4 , a radiator 5 and a water pump 6 .

[0021] The engine 2 includes: a cylinder head 201 that receives, for example, a spark plug; and a cylinder block 202 that receives, for example, cylinders; and a water jacket 203 that forms passages for coolant. The coolant flowing in the water jacket 203 is...

Abstract

A valve device (10) includes a drive device cover (80) that is placed outside a housing (20). The drive device cover (80) receives a drive device (70) of a valve (30) and a rotational angle sensor (74). The drive device cover (80) has a cover main body (82) and a connector (83). The connector (83) electrically connects the drive device (70) and the rotational angle sensor (74) to at least one external device. The connector (83) is placed on one side of the cover main body (82) where a pipe member is placed relative to the housing (20) in a perpendicular direction (D2) that is perpendicular to an axial direction (D1), and the connector (83) projects from the cover main body (82) on the one side of the cover main body (82).

Description

technical field [0001] The present disclosure relates to a valve arrangement for regulating the flow rate of coolant for an internal combustion engine. Background technique [0002] For example, WO2018 / 230664A1 discloses a valve arrangement for regulating the flow rate of coolant for an internal combustion engine. The valve device includes: a housing having a plurality of outflow ports for discharging coolant; and a valve for adjusting the flow rate of coolant discharged from each outflow port; pipeline. The valve has a rotatable shaft that rotates the valve element. The outlets are respectively arranged at different positions along the axial direction of the rotatable shaft. At a position of the housing along one side of the vertical direction perpendicular to the rotatable shaft, the duct member is mounted to the housing. Specifically, a duct member is attached to the casing at a position on the opposite side of the casing from the engine in the vertical direction. ...
