Description
本発明による圧縮機のその他の有利な構成上の特徴は以下の通りである。即ち、
・前記各開口が単一又は複数のスロットからなること。
・前記圧縮室からのガス抜き用の開口にガス導出通路が開閉可能に連結されていること。
・前記各開口は、前記圧縮ピストンがその上昇端位置又はその直前位置に達したときに該圧縮ピストンによってはじめて開かれるような箇所で前記シリンダ壁に配置されていること。
・前記吸込弁が、前記圧縮ピストンに対面する側の面に、該吸込弁と前記圧縮ピストンとの間に負圧を生ぜしめるための少なくとも一つの窪みを有すること。
Other advantageous structural features of the compressor according to the invention are as follows. That is,
-Each said opening consists of a single or several slot .
The gas outlet passage is connected to the opening for venting gas from the compression chamber so as to be openable and closable.
-Each opening is arrange | positioned in the said cylinder wall in the place where the said compression piston opens for the first time when it reaches the raising end position or the position immediately before it.
The suction valve has at least one recess for generating a negative pressure between the suction valve and the compression piston on a surface facing the compression piston.
本発明による圧縮機において、両開口２、３は圧縮ピストン移動方向に沿った単一又は複数のスロットで構成しておくことが好ましい。 In the compressor according to the present invention, it is preferable that both the openings 2 and 3 are constituted by a single or a plurality of slots along the moving direction of the compression piston.
