Claims

[Scope of utility model registration request]

A rotating body of a load fluid actuator whose fluid discharge amount is smaller than the fluid discharge amount of the sample fluid actuator is connected to the rotating shaft of the sample fluid actuator, and the fluid discharge side of the sample fluid actuator and the load fluid actuator are connected in series to the rotating shaft of the sample fluid actuator. The fluid inflow side of the fluid actuator is connected with a pipe line, and the fluid discharge side of the load fluid actuator and the fluid inlet side of the sample fluid actuator are connected with a pipe line, and the circulation system is connected by each of the actuators and the pipe line. A pipe line is connected to the pipe line connecting the fluid discharge side of the sample fluid actuator and the fluid inlet side of the load fluid actuator to return a part of the fluid discharged from the sample fluid actuator to the tank. 1. A pressure reducing valve and a check valve are provided in the pipe line connecting the fluid discharge side of the load fluid actuator and the fluid inflow side of the sample fluid actuator so that the fluid flows from the load fluid actuator side to the sample fluid actuator side. a pipe line for supplying fluid discharged from a fluid pump driven by a prime mover to the sample fluid actuator is connected to a portion of the pipe line between the check valve and the fluid inflow side of the sample fluid actuator; A pipe line is connected to a portion of the pipe line between the pressure reducing valve on the fluid discharge side of the load fluid actuator and is equipped with a load relief valve that sets the load of the load fluid actuator and allows the fluid to return to the tank. An actuator load operation test device characterized by:
