DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings and the operation thereof. This oil block 1
Is installed between the engine block 5 and the oil filter 6 to take out the oil line to the oil cooler 2 for cooling the engine oil through the oil hoses 3 and 4, as shown in FIG. One example is shown in FIGS. In these figures, the present oil block 1 includes an oil block main body and a thermostat provided inside the oil block main body.

The oil block body 20 is preferably made of a light metal having excellent touch resistance and the like, and
1 and a rectangular block 22 integral therewith,
One side surface 23 of the arc-shaped block portion 21 is a mounting surface for the oil filter 6 (see FIGS. 1 and 12), and the other side surface 24 is a mounting surface for the engine block 5 (see FIGS. See FIG. 12).

As shown in FIGS. 1 and 12,
A fitting insertion hole 25 of the main body mounting bracket 7 for mounting the main block 1 is provided through the center of the arc-shaped block 21 in the vertical direction. The main body mounting member 7 is a cylindrical body having a male screw portion 8, a nut portion 9, and a female screw portion 10, and has an oil return hole 11 in the center axis direction. In the thickness direction of the end face of the rectangular block part 22, an oil introduction screw hole 27 and an oil lead screw hole 28 are provided so as to sandwich a square positioning block part 26 integrally protruding at the center part of the end face. An oil introduction groove 29 for the oil filter 6 communicating with the oil introduction screw hole 27 is provided on the 23 side, and an engine block 5 from the engine block 5 communicating with the oil lead screw hole 28 on the engine block mounting surface 24 side. An oil introduction groove 30 is provided, and a mounting groove 31 for a ring-shaped packing 32 is further provided. In addition, screw holes 33 and orthogonal holes 34 are provided on the end face of the square block portion 22 so as to communicate with the oil introduction screw holes 27 and the oil lead screw holes 28 at right angles. Is equipped with a thermostat 40.

As shown in FIGS. 8 to 10, the thermostat 40 is screwed to a screw hole 33 of the oil block main body 20, and is fixed to a central portion of the screw plug 41. A round rod-shaped shaft 42 and an H-shaped flanged valve 43 loosely inserted in the shaft 42 so as to be movable in the axial direction.
A shape memory alloy body 44 wound and interposed between one end of the valve body 43 and the screw plug 41, and the other end side of the valve body 43 and the peripheral groove 45 of the tip end of the shaft 42. The thermostat 40 is constituted by a bias spring 48 interposed between the stop ring 46 and a spring receiver 47 for regulating movement.
The screw plug 41 is screwed into the screw hole 33, and the tip of the shaft is inserted into an insertion hole 49 provided on the distal end surface of the orthogonal hole 34 so as to be laid sideways in the orthogonal hole 34, and the engine oil When the temperature is low, the shape memory alloy body 44 is in a contracted state.
8 is pressed in the direction of the solid arrow A shown in FIG. 9, and the oil introduction path from the engine block 5 to the oil introduction path to the oil filter 6 as shown in FIG. Since the communication port 50 is open, the oil from the engine block 5 is returned to the engine block 5 through the oil filter 6 without being introduced into the oil cooler 2, and when the oil is warm and hot, the shape is reduced. When the memory alloy body 44 is extended, the valve body 43 is moved in the direction of the solid arrow B shown in FIG. 9 against the elasticity of the bias spring 48, and the communication port 50 is opened by the valve body 43 in FIG. Because it is blocked as shown in
The oil is introduced into the oil cooler 2.

The use of the present oil block 1 having the above structure is performed as shown in FIGS. That is, as shown in FIG. 12, the main body mounting bracket 7 is inserted into the insertion hole 25 of the block main body 20, and
The oil filter 6 is attached to the male screw portion 8 of the mounting bracket 7 via a ring-shaped packing so as to be screwed into the screw hole 12, and the mounting bracket is mounted to the mounting male screw portion 13 of the engine block 5 via a ring-shaped packing 32. The female thread 10 is attached by screwing. The oil introduction screw hole 27 is connected to the outlet side of the oil cooler 2 via a nipple 51 and a hose 4 screwed to the oil introduction screw hole 27, and the nipple 52 and the hose 3 and is connected to the introduction side of the oil cooler 2. When the engine is started in this state, since the engine oil is full and still cool and low temperature, the shape memory alloy body 44 in the thermostat 40 is in a contracted state and the valve body 43 is pressed by the action of the bias spring 48. The communication port 50 is open (see FIG. 6). Accordingly, the oil from the engine block 5 flows out of the engine block 5 → the oil introduction groove 30 →
The communication port 50 → the orthogonal hole 34 → the oil introduction groove 29 → the introduction hole 15 of the oil filter 6 → the oil element 16 → the outlet hole 17 → the oil recirculation hole 11 → the introduction into the oil cooler 2 via the passage 18 of the engine block 5. Don't flow. When the engine oil gets warm and hot,
The shape memory alloy body 44 in the thermostat 40 is extended, and the valve body 43 is moved against the elasticity of the bias spring 48, and the communication port 50 is closed by the valve body 43 (see FIG. 7). 5 is supplied to the oil supply passage 14 → the oil introduction groove 30 → the oil discharge screw hole 28, the nipple 52 → the hose 3 → the oil cooler 2
Inlet side → oil cooler 2 → hose 4 → nipple 5
1, the oil introduction screw hole 27 → the oil introduction groove 29 → the introduction hole 15 of the oil filter 6 → the oil element 16 → the outlet hole 17 → the oil recirculation hole 11 → the flow through the introduction path 18 of the engine block 5.

The oil block 1 according to the present invention essentially includes the oil block main body 20 and the thermostat 40 mounted inside the main body 20 as described above. Oil introduction screw hole 27 and oil discharge screw hole 28 in the thickness direction of the end face
1 to 12, the same reference numerals are given to parts corresponding to those in FIGS. 1 to 12 and, as shown in FIGS. An oil introduction screw hole 53 and an oil outlet screw hole 54 are provided in the upper surface of the upper surface 22 in the vertical direction and in a direction perpendicular to the screw holes 27 and 28 in the end surface direction. 17, the oil introduction screw hole 27 and the oil discharge screw hole 28 in the end face direction are screwed with the plugs 55 and 56, respectively, so that the square block portion 22 is formed. The upper oil introduction screw hole 53 is connected to the outlet side of the oil cooler 2 via a nipple 51 and a hose 4 screwed to the upper surface, and the oil outlet screw hole 54 is connected to a nipple 52 screwed to the oil cooler 2. Over scan 3 via a used connected to the inlet side of the oil cooler 2, and when taking out the oil line to the engine block 5 in the direction parallel, FIG. 1
As shown in FIG. 6, an oil introduction screw hole 53 and an oil extraction screw hole 54 on the upper surface of the angular block portion 22 are screwed by screwing plugs 55 and 56, respectively, and used as in FIG. And, in any use mode,
Although not shown, the oil temperature gauge and the oil pressure sensor are attached to the screw holes formed by the plugs 55 and 56 via a separately prepared adapter, and the block body 20 is mounted.
It also includes an oil block main body having a structure capable of detecting the temperature and the oil pressure of the engine oil flowing therein.

[0012]

According to the present invention, the valve body 43 of the thermostat 40 mounted in the oil block main body 20 is moved in a coil shape.
4, the valve 43 can be operated stably and reliably, so that the oil line can be reliably taken out to the oil cooler 2 and also the conventional liquid tank can be used. Therefore, the structure is simple and the size can be reduced. Accordingly, it is possible to provide an oil block that can be reduced in size, that is, small in size, that can be easily mounted, and that is inexpensive.
