Fluid control system

摘要

A first fluid system includes a thermostat portion T, a valve portion V, and an ECU 30A. The thermostat portion T includes a first thermostat 18 in a first divergent pathway PB1 and a second thermostat 19 in a second divergent pathway PB2. The valve portion V includes a valve mechanism in at least a second portion SG2 of portions SG1, SG2, SG3. In the ECU 30A, achieved is a control unit that controls the valve portion V to switch a flow control state of at least one of the valve mechanism of the valve portion V when one of an open failure and a close failure occurs in one of the thermostats 18, 19.

1. A fluid control system comprising:
a thermostat portion that includes a first thermostat in a first divergent pathway and a second thermostat of which an open valve temperature is set to be less than that of the first thermostat in a second divergent pathway, the first and second divergent pathways diverging and then converging; a valve portion that includes a valve mechanism in at least a second portion out of a first portion that is a portion located more downstream than the first thermostat in the first divergent pathway, the second portion that is a portion located more downstream than the second thermostat in the second divergent pathway, and a third portion that is a portion lying posterior to a point at which the first and second divergent pathways converge in a fluid supply pathway that includes the first and second divergent pathways and supplies a fluid to a supplying object; and a control unit that controls the valve portion to switch a distribution control state of at least one valve mechanism of the valve mechanism of the valve portion when one of an open failure that causes a thermostat to be kept open and a close failure that causes a thermostat to be kept closed occurs in one of the first and second thermostats, wherein the control unit controls the valve portion to decrease a flow volume of the fluid distributed through the third portion by controlling the valve portion to switch the distribution control state of at least one valve mechanism of the valve mechanism of the valve portion when the open failure occurs in one of the first and second thermostats.
