  • Hydraulic control and lubrication system with compressed air pre-heat circuit for rapid response at low ambient temperatures
    Patent number: 5667051
    Abstract: In a power transmission or generation apparatus having a source of heated pressurized air, the problem of achieving rapid controlled engagement of a hydraulically actuated clutch at low ambient temperatures is solved by utilizing a portion of that heated pressurized air for heating only that small control volume of hydraulic fluid within a clutch control circuit needed to achieve rapid actuation and stable control of the hydraulic clutch. Our invention is thus particularly applicable in a power transmission or generation apparatus having a gas turbine engine, or a turbocharged piston engine as the prime mover. With gas turbine engine powered units, our invention contemplates the use of compressor discharge air, rather than exhaust products for heating the hydraulic fluid. Similarly, for piston engines our invention contemplates the use of turbocharger discharge air rather than exhaust products.
