In order to continuously and automatically supply (refuel) a predetermined amount to several rotating friction parts of an industrial machine using the grease supply means 100 of the present invention configured as described above, first, the hydraulic pressure pumped by the operation of the existing hydraulic pump is shown in Fig. 4a. When simultaneously supplied (ON) to the connection hole 172 formed on one side of the intermediate fixing member 170 and the connection hole 142 formed on the lower member 140 as shown, the upper and lower honing pipes ( The upper and lower pistons 190 and 192 respectively installed in 160 are raised to reach the lower surfaces of the upper member 150 and the intermediate fixing member 170, respectively, and the rod 202 of the valve body 200 is a cylinder. As it rises on the tube 180 , the head 204 integrally formed on the upper end of the rod 202 closes the inlet hole 152 formed in the center of the upper member 150 .

In this state, when hydraulic pressure is simultaneously supplied (ON) to the connection hole 142 formed in the lower member 140 and the connection hole 174 formed on the other side of the intermediate fixing member 170 as shown in FIG. 4B, by this hydraulic action As the intermittent pin 210 moves along the connection hole 142 of the lower member 140, the wedge surface portion 212 formed at the end thereof is a wedge groove 206 formed around the lower end of the rod 202 of the valve body 200. The valve body 200 is lowered and the head 204 is lowered at the same time by the force inserted to fit the shape of the upper part so that a gap is generated between the inlet hole 152 of the head 204 and the upper member 150.

At this time, when hydraulic pressure is supplied (ON) to the upper and lower pistons 190 and 192 through the connection hole 172 of the intermediate fixing member 170, the upper and lower honing pipes 160 by this hydraulic action. The upper and lower pistons 190 and 192 respectively located in the lower part of the inner body simultaneously rise, and at the same time, the upper piston 190 pushes the grease 62 filled in the upper honing pipe 160 to the upper part, and thus As the valve body 200 rises, the head 204 closes the inlet hole 152 of the upper member 150 .

In addition, the head 204 of the valve body 200 is raised to open the connection hole 154 of the upper member 150 that was blocked when the inlet hole 152 of the upper member 150 was closed, and thus The grease 62 filled in the upper honing pipe 160 is a first grease transfer hose 15a that connects the connection hole 154 of the upper member 150 and the side of several rotating friction parts of the industrial machine by hydraulic pressure. It is continuously automatically supplied (lubricated) through the
