TOOL COMPRISING A LOW-PRESSURE BALL AND USABLE FOR POLISH SURFACES
Document Type and Number:
WIPO Patent Application WO/2012/120181
Kind Code:
A3
Abstract:
The invention relates to a tool comprising a low-pressure ball and usable for polishing surfaces, consisting of a main body (1) that is rendered watertight by means of O-ring seals (8) and a cover (6) which houses a valve lifter (5), the piston (5d) of which acts on a guide rod (4) that transmits the force to a sleeve (3) to which the ball is coupled (2), comprising an opening (1b) that coincides with an inner groove (17) and another groove (17) of the valve lifter (5), and an entry cutout (5c). The circuit that provides the hydraulic fluid includes a tank (10), a filter (11), a hydraulic pump (12), hoses (13), a manometer (14), an adjustable pressure relief valve (15) and coupling nuts (9). The pump (12) is part of the equipment that circulates the cutting fluid through the system and the hydraulic pressure is controlled by the valve (15) that regulates the pressure exerted on the ball.
