Title
(DE) PNEUMATISCHES ROTATIONS-WERKZEUG
(EN) PNEUMATIC ROTARY TOOL
(FR) OUTIL ROTATIF PNEUMATIQUE
Abstract
(EN) A pneumatic rotary tool has a housing formed primarily from plastic so that the weight and price of the tool are substantially reduced. The air motor is formed for economic assembly while permitting greater structural stability should the housing deflect under an impact. The tool includes a torque selector which controls the amount of pressurized air allowed to enter the air motor, thereby controlling the torque output of the motor. The user may adjust the torque selector to a number of set positions which correspond to discrete torque values. The tool additionally incorporates early and late stage exhaust ports, so that backpressure within the air motor does not slow motor rotation or decrease tool power.
(FR) L'invention concerne un outil rotatif pneumatique comprenant un logement fabriqué principalement à base de plastique, de façon que le poids et le prix de cet outil soient sensiblement réduits. Le moteur pneumatique est conçu pour un montage économique, permettant une plus grande stabilité structurelle au cas où le logement venait à se braquer lors d'un impact. Cet outil comprend un sélecteur de couple qui commande la quantité d'air sous pression entrant dans le moteur pneumatique, ce qui permet de commander le couple de sortie du moteur. L'utilisateur peut régler le sélecteur de couple de façon à obtenir plusieurs valeurs correspondant à des valeurs de couple discrètes. Cet outil comprend également des orifices d'échappement de limitation d'avance et de retard, afin que le reflux dans le moteur pneumatique ne ralentisse pas la rotation du moteur ou ne diminue pas la puissance de l'outil.
