<p>The present invention relates to a rotary valve for a grease supply apparatus that supplies grease stored in a container (3) by controlling lifting operation of a plate (2) by a cylinder (1). The rotary valve includes a stationary block (10) installed in a valve housing (12) and having a compressed air supply port (P), cylinder lowering and lifting ports (A, B), a can separating port (C), and a discharge port (R); and a rotary block (20) coming into contact with the stationary block (10) and rotating at even angle by a lever (26), and having a plurality of channels to supply compressed air introduced into the supply port (P) to the lowering port (A) or the lifting port (B), or discharge the compressed air to the discharge port (R). The can separating port (C) communicates with the supply port (P) at the even position where the rotary block rotates to supply the compressed air to the lifting port (B). The plate is easily lifted and lowered, or at a neutral position according to the evenly rotating position of the rotary block by the lever, and when the compressed air is supplied to the lifting port, the supply port and the can separating port communicate with each other, so that the compressed air is supplied to the container to easily separate the plate.</p> |
