The piston rod is placed in a cooling device with cooling II, a sealed space is formed along the axial direction of the piston rod, and a refrigerant is sealed inside the piston rod, and the crank side of the piston rod is placed on the low temperature side. This system utilizes the difference in inertia between the head end of the compressor and the inertia when the piston returns to the crank side, and transfers the condensate condensed on the low temperature side to the high temperature piston side. By moving it to the temperature side, evaporating it there, and returning it to the crank side, which is the low temperature side, it was possible to cool the high temperature side.
［実施例］
以下本発明に係るピストンロッド冷却装置の好適一実施
例を添付図面に基づいて説明する。[Embodiment] A preferred embodiment of the piston rod cooling device according to the present invention will be described below with reference to the accompanying drawings.
添付図面は往復圧縮量に本発明のピストンロッド冷却装
置を適用したものである。The attached drawings show the application of the piston rod cooling device of the present invention to reciprocating compression.

流体を、そのピストン２の往復動により夫々交互に吸入
・圧縮を繰り返りようになっている。In Fig. 1, J3 is a cylinder, in which a piston 2 is provided so as to be able to reciprocate, and fluid such as air is supplied to the cylinder chambers 3.4 on both sides of the head end side 1a and crank side 1b. By reciprocating the piston 2, suction and compression are repeated alternately.

このクロスヘッド７は、クランク軸の回転を往復動とし
てピストンロッド５に伝）エラる。This crosshead 7 transmits the rotation of the crankshaft as a reciprocating motion to the piston rod 5.
ピストンロッド５内には、その軸方向に沿って密閉され

冷媒９が封入される。A sealed space 8 is formed in the piston rod 5 along its axial direction, and a refrigerant 9 such as water or fluorocarbon is sealed within this space 8.

The piston rod 5 is cooled by air cooling or by surrounding it with a water jacket and mildly acidic to cool it.

１ａの慣性力が約１．５倍太きくなる。When the piston 2 is reciprocated by the piston 5, the inertia force when moving to the l\radend 1a side and the inertia force when moving to the crank side 1b are equal to the inertia force at the head end 0111a. 101 for the average value

移動して凝縮されるためピストンロッド５を冷却する。Therefore, the refrigerant 9, which has 11 people in the space 8, is condensed by heat exchange with the low temperature side 10 on the crank side 5b, and the condensed liquid moves to the piston side 5a, which is the high temperature side, due to the above-mentioned inertial force difference. There, the evaporated gas moves to the outer crank side 5b and is condensed, thereby cooling the piston rod 5.
