Definitions
- the present invention relates to a thermoactuator and its mounting structure, for example, to a thermoactuator that is mounted on an engine and advances and retracts a shaft by expansion and contraction of wax accompanying a temperature change on the engine side, and its mounting structure.
- thermoactuator in which a shaft advances and retreats when wax contained in a case expands and contracts due to a temperature change.
- this thermoactuator has been proposed to use this thermoactuator as a driving source for a shutter (shielding plate) for a radiator of an automobile.
- Patent Document 1 discloses an engine ventilation shut-off device that includes a thermoactuator and can respond immediately even if the engine load fluctuates rapidly.
- FIG. 8 shows a cross-sectional view of the ventilation blocker disclosed in Patent Document 1. As shown in FIG. *
- the ventilation blocker 200 shown in FIG. 8 is configured to open and close a shielding plate (not shown) connected to the distal end side (left direction in the drawing) of the shaft 201 by the forward and backward movement of the shaft 201.
- the shielding plate opens the ventilation passage of the radiator when the engine is cooled, and closes the ventilation passage at other times, and is provided in the ventilation passage so as to be openable and closable.
- the ventilation blocker 200 has a rear end (right end in the drawing) of a shaft 201 coupled to a diaphragm 203 stretched in a case 202 and is pushed backward by a spring 204.
- a vacant chamber 205 is formed in front of the diaphragm 203 and is connected to an intake manifold (not shown) of the engine through a pipe 206.
- a vacant chamber 207 is formed behind the diaphragm 203, and is connected to an intake manifold of the engine through a pipe 209 through a valve 208.
- the valve 208 is provided so that a substantially conical valve body 210 is pressed against a valve seat 212 formed in the case 202 by a spring 211 and closed. Further, when the thermo-element 213 attached to the rear end of the case 202 and installed in the radiator 215 is heated and a thermal expansion material such as wax incorporated therein expands and pushes out the piston 214, the piston 214 becomes a valve body. 208 is pushed away from the valve seat 212 to open.
- a thermoactuator 216 is configured by the mechanism including the piston 214 and the thermoelement 213 for moving the piston 214 back and forth. *
- the valve 208 is closed, and the vacant chamber 205 is decompressed by the negative pressure of the intake manifold, and the diaphragm 203 is drawn. In this state, the shaft 201 protrudes (the shielding plate is closed).
- the negative pressure of the intake manifold decreases as the engine throttle valve opens greatly.
- the pressure in the vacant chamber 205 rises, and the shaft 201 retreats while pushing the diaphragm 203 into the vacant chamber 207 by the force of the spring 204, and the shielding plate opens.
- thermoactuator 216 is used to realize the opening / closing operation of the shielding plate for ventilation control.

- connection between the support part 52 and the element case 51 and the connection between the support part 52 and the cylinder part 53 are performed by bending the end parts 52a and 52b of the support part 52 inward as shown in the figure. Since it is based on the so-called caulking process to be fitted to the object, there is a possibility that a problem may occur. That is, when the support portion 52 of the thermo element 60 is screwed into the engine side, shear stress (twist) is generated in the support portion 52, and the end portion 52a of the support portion 52 that has been crimped may be deformed.
