動ポンプ。[Claims for Utility Model Registration] (1) A connecting rod that is pivotally supported in the crankcase via the crankshaft, and a piston that is connected to the tip of the connecting rod with a pin and is capable of reciprocally sliding inside the cylinder body. a reciprocating pump comprising: a cylinder large-diameter portion and a cylinder small-diameter portion that allow the cylinder body to communicate with each other; A large-diameter piston portion and a small-diameter piston portion constituting the piston means are respectively slidably disposed in a water-tight manner via packing means, and a piston large-diameter portion and a small-diameter piston portion are defined by the large-diameter piston portion and the small-diameter piston portion, respectively, through packing means. A large-diameter chamber is formed in which a large-diameter suction port having a suction valve and a large-diameter discharge port having a discharge valve are provided in the large-diameter chamber, and a piston small-diameter portion is provided at the tip side of the small-diameter portion of the cylinder. A small-diameter chamber is formed, a small-diameter discharge port having a discharge valve is provided in the small-diameter chamber, and a small-diameter portion has a suction valve in the small-diameter portion of the piston that allows communication between the small-diameter chamber and the large-diameter chamber. A reciprocating device characterized in that an inlet is provided, and the small-diameter discharge port is communicated with the large-diameter discharge port by a communication passage provided with an opening/closing means, and is also communicated with the outside via a branch passage. dynamic pump. (2) The reciprocating pump as set forth in claim (1) of the utility model registration claim, characterized in that pressure regulating means is provided on the secondary side of the large-diameter discharge port and between the opening and closing means. .
