Claims

[Scope of utility model registration request]

A cylinder pump in which a piston is driven by a reciprocating actuator to reciprocate within a cylinder, thereby sucking fluid into the cylinder from a fluid supply source and discharging the fluid sucked into the cylinder through a discharge nozzle. is a double-acting type having first and second fluid inlets and outlets at both ends, and the first and second fluid inlets can be switched to the fluid supply source side and the discharge nozzle side, respectively. a flow path switching valve, and one of the first and second flow path switching valves that moves the piston to either side of the first or second fluid inlet/outlet and is connected to the one side; A cylinder pump characterized in that it is provided with a control device that switches one side to the discharge nozzle side and the other side to the fluid supply source side.
