Patent ID: 8646549

Claim:
A drilling machine, comprising: a drilling bit; a prime mover; a pump system operatively coupled to the prime mover; a compressor; a hydraulic wet mechanical clutch coupled to the prime mover and compressor, wherein the hydraulic wet mechanical clutch is coupled to the prime mover with a clutch-to-prime mover coupling, and the hydraulic wet mechanical clutch comprises a compressor end housing coupled to the clutch through a clutch spacer, wherein the clutch spacer allows the compressor to be spaced from the prime mover; wherein the compressor is allowed to provide air and is restricted from providing air in response to the hydraulic wet mechanical clutch being in engaged and disengaged conditions, respectively, and the hydraulic wet mechanical clutch is moveable between the engaged and disengaged conditions during operation of the prime mover; and a fluid heat exchange system comprising a sump and a heat exchanger, which flows heat from the hydraulic wet mechanical clutch, wherein the heat exchanger is positioned proximate a radiator of the drilling machine and the radiator cools the heat exchanger by convection from air drawn by the radiator, wherein the fluid heat exchange system flows hydraulic fluid from the hydraulic wet clutch to the sump, then to the heat exchanger to reduce the hydraulic fluid temperature and then back to the hydraulic wet mechanical clutch, and wherein the sump is positioned proximate the pump system.
