Claims (1)
ピストン部を駆動軸を介して連結し、この駆動軸
に設けたボールねじ部に増圧機本体に回転自在に
支承された歯車を螺合してこの歯車を所定時間経
過するたびに回転の向きが逆となるサーボモータ
に連結し、他方、各高圧シリンダの液室は液室へ
の流体流入を許容するチエツク弁を介して液圧ポ
ンプに接続すると共に、液室からの流体流出を許
容するチエツク弁を介して噴射ノズルに接続した
ことを特徴とする往復動増圧機。 The piston parts of a pair of high-pressure cylinders installed opposite to each other on the pressure intensifier body are connected via a drive shaft, and a gear rotatably supported on the pressure intensifier body is screwed into a ball screw part provided on this drive shaft. This gear is connected to a servo motor that rotates in the opposite direction every time a predetermined period of time elapses, and the liquid chamber of each high-pressure cylinder is connected to a hydraulic pump via a check valve that allows fluid to flow into the liquid chamber. A reciprocating pressure intensifier characterized in that it is connected to an injection nozzle via a check valve that allows fluid to flow out from the liquid chamber.
