Abstract: front page image
(EN)The problems such as crushing and wear of cushion by the thermal expansion of a communicating are resolved to thereby inhibit the occurrence of noise. The pump unit comprises a pump main body (1) for ejection of compressed air; a communicating tube of elastomer having its one end fitted to an ejection port of the pump main body (1); a pump holding part (2) for retaining a portion of the part of the communicating tube other than its part fitted to the ejection port; cushions (13a,13b) provided on the outer circumferential surface of the pump main body (1); and films (15a,15b) provided on the surfaces of the cushions (13a,13b). Each of the films (15a,15b) has a smooth surface, and the frictional coefficient of the smooth surface is smaller than that of the cushions (13a,13b).
(FR)L’invention vise à résoudre les problèmes tels que l’écrasement et l’usure de coussinets causés par l’expansion thermique d’une communication et, ainsi, à permettre de réduire la survenue de bruit. L’unité de pompe comporte un corps principal de pompe (1) servant à l’éjection d’air comprimé ; un tube de communication en élastomère possédant une extrémité montée sur un orifice d’éjection du corps principal de pompe (1) ; une partie de retenue de pompe (2) servant à retenir une partie de la partie du tube de communication autre que la partie montée sur l’orifice d’éjection ; des coussinets (13a, 13b) situés sur la surface circonférentielle extérieure du corps principal de pompe (1) ; et des films (15a, 15b) disposés sur les surfaces desdits coussinets (13a, 13b). Chacun de ces films (15a, 15b) présente une surface lisse, le coefficient de friction de ladite surface lisse étant inférieur à celui des coussinets (13a, 13b).
(JA) 連通管の熱膨張によるクッションの潰れやクッションの磨耗の問題を解決して騒音の発生を抑制する。ポンプユニットは、圧縮した空気を吐出するポンプ本体1と、ポンプ本体1の吐出口に一端が嵌合された、弾性体よりなる連通管と、この連通管の上記吐出口との嵌合部以外の部分の一部を保持するポンプ固定部2と、ポンプ本体1の外周面に設けられたクッション13a、13bと、クッション13a、13bの表面に設けられたフィルム15a、15bと、を有する。フィルム15a、15bは平滑面を備え、該平滑面の摩擦係数が、クッション13a、13bの摩擦係数より小さい。
