Abstract
A machine tool and method provides integral cooling to the tool, by employing exhaust air from the drive motor. The exhaust air is suitably allowed to expand within the body of the tool, advantageously cooling the tool.
Claims20
A method of cooling an air actuated machine tool comprising the steps of:
- employing exhaust air derived from actuating the machine tool to cool the machine tool,
- wherein said exhaust air is supplied from an exit point of an actuation motor to an interior portion of the machine tool via a supply tube communicated between the exit point and the interior portion, and
- wherein said employing step includes allowing expansion of the exhaust air within an interior portion of the machine tool to assist in the cooling thereof.
A cooling system for an air powered machine tool, comprising:
- an exhaust air re-director for capturing exhaust air from a driving motor and supplying it to a body of the air powered machine tool;
- and
- a chamber within said body for receiving said exhaust air as cooling air,
- wherein said driving motor exhausts air via an exhaust point adjacent a location where driving supply air is provided to said motor, and wherein said exhaust air re-director comprises a supply tube connected between said exhaust point and the body of the machine tool.

An integrally cooled air powered machine tool, comprising:
- an exhaust air capture for capturing exhaust air at a capture location from a driving motor;
- an expansion chamber receiving said exhaust air and enabling expansion thereof to enable cooling thereof,
- wherein said capture location is at a position distal from a location where said driving motor transfers power to said machine tool, and
- wherein said exhaust air capture includes a transfer tube for transferring exhaust air from said capture location to said expansion chamber.
