<p>PURPOSE: To certainly carry out degassing and priming of a pump by piping and connecting a receptacle on which an orifice to open to atmospheric air is provided to the top point of a suction chamber to be connected to a suction opening of the pump. CONSTITUTION: A receptacle 3 having an orifice s to open to atmospheric air on its upper part and having a means constituted by storing a ball 9 in a guide element 10 free to float so as to prevent escape of liquid through the orifice 8 is connected to the top point of a suction chamber 2 through a second pipe 5. The suction chamber 2 is connected to a tank 1 through a first pipe 6 in which a filter 11 is interposed, connected to a suction opening of a pump 4 and a second hydraulic pressure circuit 7 is connected to a discharge port of the pump 4. Consequently, it is possible to certainly carry out degassing and priming of the pump 4 through the receptacle 3.</p> |
