Claims (4)

プランジャーと、プランジャー駆動部と、前記プランジャーを収納したシリンダーと、を有するポンプ装置であって、前記プランジャーには、長手方向に連通する連通孔が形成され、該連通孔はプランジャー後退時に該孔を通じて、移送媒体を吸入し、プランジャー前進時にシリンダーのプランジャー前進方向後端面に形成された吐出口を通じて前記移送媒体を吐出するものであるポンプ装置。 A pump device having a plunger, a plunger drive unit, and a cylinder housing the plunger, wherein the plunger is formed with a communication hole communicating in the longitudinal direction, the communication hole being a plunger A pump device that sucks the transfer medium through the hole when retreating, and discharges the transfer medium through a discharge port formed on the rear end surface of the cylinder in the plunger advance direction when the plunger advances. 長手方向に連通する連通孔が形成されているプランジャーと、プランジャー駆動部と、前記プランジャーを収納したシリンダーと、前記プランジャー駆動部の制御部とを有し、かつ前記プランジャー駆動部の制御部は吐出モードおよび吸引モードを設定可能で、前記吐出モードではプランジャーが前方向に移動し、シリンダー内に充填された移送媒体をシリンダーに形成された吐出口から吐出し、また吸引モードではプランジャーが後方に移動し、前記孔から移送媒体を吸入するように制御するものであるポンプ装置。 A plunger having a communication hole communicating in the longitudinal direction; a plunger driving unit; a cylinder housing the plunger; and a control unit for the plunger driving unit; and the plunger driving unit. The controller can set the discharge mode and the suction mode. In the discharge mode, the plunger moves forward, the transfer medium filled in the cylinder is discharged from the discharge port formed in the cylinder, and the suction mode. Then, the pump device that controls the plunger to move backward and suck the transfer medium from the hole. 前記連通孔からの移送媒体の吸引方向及び前記吐出口からの移送媒体の流通方向を規制する流通方向規制手段を有する請求項１又は２に記載のポンプ装置。 3. The pump device according to claim 1, further comprising a flow direction regulating unit that regulates a suction direction of the transfer medium from the communication hole and a flow direction of the transfer medium from the discharge port. 前記流通方向規制手段は、チェックバルブであることを特徴とする請求項３に記載のポンプ装置。
The pump device according to claim 3, wherein the flow direction regulating means is a check valve.
