し下げる。 Next, the present invention will be explained in detail with reference to the embodiments shown in the drawings. Reference numeral 10 denotes a temperature control valve of the present invention, and reference numeral 14 is a first valve seat attached to a partition plate 12 in a cooling water channel flowing from the bottom to the top, and is formed on a frame 16 so as to face downward. Reference numeral 18 denotes a first valve body, which is pressed upward by a spring 20 interposed between it and the frame 16 so as to come into contact with the first valve seat 14 . Reference numeral 22 denotes a wax-type temperature sensing element, which is fixed to the first valve body 18 and has a piston rod 22a protruding from its upper end, the tip of which abuts against the frame 16. Therefore, when the temperature rises, the piston rod 22a protrudes from the temperature sensing element 22 and pushes down the first valve element 18 against the elastic force of the spring 20.

いればよい。 Reference numeral 24 denotes a second valve seat, which is formed on the frame 16 below the first valve seat so as to face downward on the outer periphery. Reference numeral 26 denotes a second valve body peripheral portion, which is made of an elastic body and is provided protruding from the outer periphery below the first valve body 18.
It constitutes a second valve body together with the valve body 18, and the second valve seat 2
4 so that they are in surface contact. The first valve body contact surface 18a on the upper surface of the circumference of the first valve seat 18 and the second valve body circumference 2
The axial distance between the upper surface of 6 and the second valve body abutting surface 26a is formed to be slightly smaller than the axial distance between the first valve seat 14 and the second valve seat 24, so that when closing the valve, The first valve body contact surface 18a is the first valve seat 14
The second valve element abutting surface 26a abuts the second valve seat 24 before abutting the second valve body abutting surface 26a. Note that the second valve body does not necessarily need to be fixed to the first valve body as in this embodiment, but may be provided upstream of the first valve body in the above-mentioned dimensional relationship.
この弁は次のように作動する。 This valve operates as follows.
低温時には第１図に示すように第１，第２弁体
当接面１８ａ，２６ａはともに第１，第２弁座１
４，２４に当接し閉弁状態となり、高温時には第

る。 At low temperatures, as shown in FIG.
4 and 24 and the valve is closed, and when the temperature is high, as shown in FIG.
are both separated from both valve seats 14, 24 and enter the valve open state.

い。 Furthermore, in this valve, when the cooling water temperature decreases and the valve changes from the open state to the closed state, the second valve body abutting surface 26a shown in FIG. 4 abuts the second valve seat 24, and the first valve body abuts. The contact surface 18a passes through a semi-closed state in which it is not in contact with the first valve seat 14. In this half-closed state, if foreign matter such as casting sand is mixed in the cooling water, even if the foreign matter is caught between the second valve body contact surface 26a and the second valve seat 24, this contact Since the surface 26a is made of an elastic body and is in surface contact with the second valve seat 24, the foreign matter is wrapped in the elastic body, and the flow of cooling water almost stops, so that the first valve body abutting surface 18
No new foreign matter will flow into the cooling water above a, and the foreign matter that is already there will be absorbed by the second valve body contact surface 2.
It precipitates near 6a. Therefore, the first
When the valve body abutting surface 18a abuts against the valve seat 14 and the valve is in the closed state, no foreign matter is caught in this joint surface.
よつてこの弁では冷却水中に異物が混入してい
ても確実に完全な閉弁が実現する。 Therefore, this valve can reliably close the valve completely even if foreign matter is mixed in the cooling water.
