Patent ID: 7364032

Claim:
A chip discharge system to separate metal chips contained in coolant discharged from a machine tool comprising a fluid dispersing arrangement that at least partially removes said chips retained in said system, said fluid dispersing arrangement having a fluid discharge pipe with at least one fluid dispersing hole, and a deflector plate to at least partially deflect and disperse fluid flowing out from the fluid dispersing hole, said fluid discharge pipe including a purging arrangement, said purging arrangement including at least one purge opening to discharge a portion of said coolant from said fluid discharge pipe, said at least one purge opening having a cross-sectional area that is greater than a cross-sectional area of each of said fluid dispersing holes, that includes a fluid entry opening designed to enable fluid to enter a passageway in said fluid discharge pipe, a purge opening designed to enable the discharge of a portion of said fluid from said passageway of said fluid discharge pipe, a plurality of fluid dispersing holes in communication with said passageway to enable fluid flow out of at least one side of said fluid discharge pipe, and a deflector plate to at least partially deflect and disperse fluid flowing out from the fluid dispersing holes to form a fluid spray pattern onto at least a portion of said filter arrangement, said deflector plate connected to said fluid discharge pipe, said fluid dispersing holes located on a lateral face of said fluid discharge pipe, said purge opening having a cross-sectional area that is greater than a cross-sectional area of each of said fluid dispersing holes, said purge opening having a cross-sectional area that is less than a cross-sectional area of said fluid entry opening.
