<p>PURPOSE: To realize silent actuation and uniform content flowing by connecting control cylinders to each other via a connection pipe by synchronous mechanism and changing volumes of the control cylinders in proportion to movements of the pistons. CONSTITUTION: Drive pistons 5A, 5B respectively form units with control pistons 4A, 4B and pump pistons 6A, 6B. A piston 2A moves horizontally as a whole simultaneously with the drive piston 5A. When this movement occurs, the control piston 4A reduces a free space in a control cylinder 18A, whereby the oil of an actuation fluid existing in this space is actuated to flow to a control cylinder 18B of a downstream reciprocating pump through a connection pipe 20 and a flow adjusting valve 21. Here, the oil pushes the control piston 4B to move it in a direction reverse to the control piston 4A, and the piston 2B moves rightwards simultaneously.</p> |
