Claims

[Scope of utility model registration request]

A flow control valve 3 is interposed in the pump line 1 or tank line 2 connected to the hydraulic motor 5 that drives the indexed object, and the flow control valve 3 is slidably connected to the spool 16 that opens and closes the variable orifice. The flow control valve 3 and the cam 7 are arranged in a position indexing device that is provided with a cam 7 that is interlocked with the hydraulic motor 5 to cause the spool 16 to respond to the shape of the cam.
The main body casing 25, which houses the cam 7, is divided into a cam storage case part 29 which houses the cam 7, and a side case part 30, in which the flow rate control valve 3 is disposed. The cam of the cam 7 is disposed so that it can be guided out from the side case part 30 into the main body casing 25, while the cam of the cam 7 is disposed at one end of the lever 8 rotatably supported in the cam storage case part 29. Contactor 12 that contacts the surface
and the other end of the lever 8 is connected to the spool 16.
