給するのが難しい欠点があつた。 Therefore, the air compressed and supplied to these tools is filled with oil in order to replenish the rotational drive parts of the tools.
An oiler (oil supply device) is installed in the piping, and oil is mixed into the air in the form of a mist.
As the air supply distance becomes longer, the mist-like oil condenses inside the hose and becomes drop-like, making it difficult to supply air in an ideal mist-oil state to the tool.

Yes, the joint main body A is provided with a tool connecting part 2, a coupler fitting part 3, and a hose connecting part 4 formed on the circumferential surface of a cylindrical body that passes through a ventilation hole 1 in the center, and the tool connecting part 2 and the hose connecting part 4 is formed with an appropriate connection structure, for example, a male thread structure (in the illustrated example, a female thread structure may be used depending on the thread structure to be connected), and a small diameter portion 5 is formed on the smooth outer peripheral surface of the coupler fitting portion 3. A small hole 6 penetrating the ventilation hole 1 is formed in the small diameter portion 5, and an annular groove for fitting the O-rings 7, 7 and the fixing ring 8 is provided at the left and right ends of the coupler fitting portion 3. 9, 9, and 10 are cut out, and the coupler B has an appropriate valve structure in the upper protrusion of a short cylindrical body that passes through the fitting hole 11 into which the coupler fitting part 3 of the joint body A is fitted. A small hole 13 is bored through the hole 12, one end of the small hole 13 is opened to the insertion hole 11, and the other end is opened to the oil pipe 1.
4, the fitting hole 11 has a large diameter hole 16 stepped on its smooth inner peripheral surface, and the small hole 13 is opened in the large diameter hole 16, and the valve structure 12 has, for example, , a ball valve 12' in which a ball 18 is pressed against a valve seat 19 by a spring 17.
The coupling part 15 of the oil pipe 14 is formed by threading a nipple 15' into the opening at the other end, and the coupler B is inserted into the coupling hole 11 in the coupler fitting part 3 of the joint body A. , and O-rings 7, 7 into the ring grooves 9, 9.
Rotatably and watertightly fitted (fit the fixing ring 8 into the ring groove 10 to prevent the coupler B from coming off)
Then, an annular oil supply passage 20 is formed between the outer circumferential surface of the small diameter portion 5 of the fitted coupler fitting portion 3 and the inner circumferential surface of the large diameter hole 16 of the fitting hole 11. It consists of an attached joint.

る。 ...Function (1)...In the above configuration, the joint with the oil supply coupler of the present invention is connected to the joint body A.
The tool connection part 2 of the is directly connected to a tool, for example, an air driver 21, the hose 22 through which compressed air is supplied is connected to the hose connection part 4, and the nipple 15' of the coupler B is connected with oil. It is used by connecting pipes 14,
When a tool such as the air driver 21 is operated in this state, the oil entering from the nipple 15' of the coupler B is controlled by the ball valve 12', and the necessary amount of oil is distributed from the small hole 13 to the annular oil passage 20 to
It flows into the joint body A in the order of small hole 6 → ventilation hole 1, and at the exit of small hole 6, it is made into a mist by the compressed air in ventilation hole 1 and mixed homogeneously into the compressed air, and as it is, the tool rotates. Supplied to the drive part.

ムーズに流入する。(2)...The coupler B is rotatably and watertightly fitted in the coupler fitting part 3 of the joint body A, but the annular oil feed passage 20 is connected in a circular manner between the two A and B, so to speak. Since it is formed so as to surround the outer periphery of the portion 3, oil flows into the annular oil passage 20 through the small hole 13, and then
It flows smoothly into the small hole 6 of the joint body A and then into the ventilation hole 1 in that order.
