Title (EN) RECIPROCATING COMPRESSOR AND CONTROL METHOD THEREFOR
(FR) COMPRESSEUR À PISTON ET SON PROCÉDÉ DE COMMANDE

Abstract:
(EN) The purpose of the present invention is to provide a reciprocating compressor which is a compact, light-weight, portable air compressor such that deterioration of performance due to problems such as wear on the surface finish of the cylinder when the compressor is used for a long period of time outside the operating temperature range thereof is prevented. To achieve this, the cylinder temperature is detected, and control is carried out so that the compressor is restarted at a lower restart pressure when the temperature is lower than a prescribed value and stopped (and also restarted, preferably) at a low pressure when the temperature is higher than a prescribed value.
(FR) La présente invention a pour objet de fournir un compresseur à piston qui est un compresseur d'air compact, léger, portable de telle sorte qu'une détérioration des performances, due à des problèmes tels que l'usure sur le fini de surface du cylindre lorsque le compresseur est utilisé pendant une longue période en dehors de la plage de température de fonctionnement de ce dernier, soit empêchée. À cet effet, la température du cylindre est détectée et une commande est réalisée de telle sorte que le compresseur soit remis en marche à une pression de redémarrage inférieure lorsque la température est inférieure à une valeur prescrite, et soit arrêté (et également remis en marche, de préférence) à une basse pression lorsque la température est supérieure à une valeur prescrite.
(JA) 小型軽搬型の空気圧縮機である往復動圧縮機において、圧縮機が使用温度範囲外で長時間使用された場合であっても、シリンダ表面処理の摩耗などによる性能低下を引き起こさないようにするために、シリンダ温度を検知して、温度が規定値より低い場合はより低い再起動圧力で再起動させ、温度が規定値より高い場合も低い圧力で停止(好ましくは再起動も)するよう制御する。
