Title (EN) FLUID POWERED PERCUSSION TOOL
(FR) OUTIL À PERCUSSION ENTRAÎNÉ PAR UN FLUIDE
Abstract: front page image
(EN)Fluid-powered percussion tool 1, comprising a housing 2 with a supply channel for pressurised fluid 3, a percussion mechanism 4, a swinging joint 5 arranged to carry the percussion mechanism 4 relative to the housing 2 at a point situated between the forward end A and the rear end B of the percussion mechanism 4, at least one elastically resilient element 6 arranged between the housing 2 and the percussion mechanism 4 at a distance from the swinging joint 5 and arranged to load the percussion mechanism 4 against a neutral position in the housing 2 and to absorb the vibrational movements of the percussion mechanism 4, and a flexible connection for pressurised fluid 7 for distribution of pressurised fluid from the supply channel for pressurised fluid 3 to the percussion mechanism 4. The elastically resilient element 6 comprises a conical spring 8. The flexible connection for pressurised fluid 7 comprises a hose 11.
(FR)L'invention porte sur un outil à percussion entraîné par un fluide 1, comprenant un boîtier 2 avec un canal d'alimentation pour un fluide sous pression 3, un mécanisme de percussion 4, un raccord oscillant 5 agencé pour porter le mécanisme de percussion 4 par rapport au boîtier 2 en un point situé entre l'extrémité avant A et l'extrémité arrière B du mécanisme de percussion 4, au moins un élément élastique 6 disposé entre le boîtier 2 et le mécanisme de percussion 4 à une certaine distance du raccord oscillant 5 et agencé pour charger le mécanisme de percussion 4 contre une position neutre dans le boîtier 2 et pour absorber les mouvements de vibration du mécanisme de percussion 4, et une liaison souple pour fluide sous pression 7 pour la distribution du fluide sous pression du canal d'alimentation pour fluide sous pression 3 au mécanisme de percussion 4. L'élément élastique 6 comprend un ressort conique 8. La liaison souple pour fluide sous pression 7 comprend un tuyau souple 11.
