A pump apparatus configured with a first pump for pumping working fluid in accordance with a reciprocation of a piston using a space between a first open/close valve for suction and a second open/close valve for discharge as a pump chamber. The pump apparatus is also configured a first flow passage for supplying the working fluid from a supply source to an operation subject via the first open/close valve, the pump chamber, and the second open/close valve in accordance with an operation of the first pump. A second flow passage supplies the working fluid pumped by a second pump, which is different from the first pump, to the pump chamber.
