Abstract
Description
Claims (4)
- 1.入口側および/または出口側(4,5)に消音装置を設けられたねじロータ 機械において、入口ポートおよび/または出口ポート(たとえば6)付近に取付 けられたラバール・ノズル(8)は前記ノズル下流に設けられ、ほぼ一定のばね 力に抗して軸方向に移動しうる弁体(9)と共働して、緩衝力(15)の影響に よつて制御される最少流通面積(8A)に容量停止から全容量まで機械の容量が 増加するときゼロから最大容量まで連続的に増加し、流量を前記最小流通面積( 8A)において音速の直ぐ下に維持することを特徴とする、前記ねじロータ機械 。
- 2.弁体(9)はハウジング(13)に収容された液体充填シリンダ内で移動し うるピストン(12)に連結され、前記ピストンは絞弁(15)を有する導管( 16)内に液体流を駆動するように作用する、請求項1に記載の機械。
- 3.ハウジング(13)は前記導管の管ベンド(7)付近で機械の入口導管およ び/または出口導管(5,7)の外部に取付けられ、ピストンロッド(10)は ピストン(12)と弁体(9)を連結しかつ管ベンド(7)の壁を貫通している ことを特徴とする、請求項2に記載の機械。
- 4.絞弁(15)を有する導管(16)はハウジング(13)の壁の内部または 外部に設けられ、絞弁(15)はそれを調節する装置を設けられまたハウジング 外側に固定装置(17)を有することを特徴とする、請求項3に記載の機械。
