摘要： This invention pertains to a rotary disk tool which utilizes pressurized water as the working fluid. When an operator engages a trigger on a novel control handle and valve assembly, pressurized seawater enters the rotary disk tool through the control handle and valve assembly into a seawater powered vane motor. The shaft of the seawater powered vane motor, is coupled to a drive gear. The drive gear, in turn, is in operative engagement with a driven pinion coupled to an output shaft which drives an abrasive disk. Seawater exhausted from the motor into a gear and pinion housing provides lubrication for the drive gear, driven pinion, and the bearings used with the gear and pinion. The seawater is then exhausted from the housing as a fan spray directed onto the back of the abrasive disk so as to reduce drag of the disk in water and to flush away loose material from the work surface.

摘要： This invention pertains to a rotary impact tool which utilizes pressurizedeawater as the working fluid. When an operator engages a trigger on a novel control handle and valve assembly, pressurized seawater enters the rotary impact tool through the control handle and valve assembly and a reversing valve into a seawater powered vane motor. The shaft of the seawater powered motor, is coupled to a twin hammer impact mechanism by a novel coupling assembly with rotation of the vane motor driving the impact mechanism which translates vane motor power into impact torque. The impact mechanism is, in turn, sealed within a cavity in the front portion of the housing of rotary impact tool with lubrication and cooling of the impact mechanism being provided by a water soluble oil based lubricant which fills the cavity.
