Abstract:
A hybrid thermostat valve for a machine includes an inlet port, a first outlet port and a second outlet port. A sealing member located between the inlet port and the first outlet port includes holes providing a first channel of fluid communication between the inlet port and the first outlet port. A valve element located between the inlet port and the first outlet port selectively allows fluid communication between the inlet port and the first outlet port through the first channel. A bypass valve element located between the inlet port and the second outlet port selectively allows fluid communication between the inlet port and the second outlet port. Further, an actuator selectively controls position of the sealing member to provide a second channel of fluid communication between the inlet port and the first outlet port based on a current work cycle segment being performed by the machine.
