Abstract
A reservoir is provided having an upper reservoir body connected to a lower reservoir body. The reservoir includes and inlet port and an outlet port that are separated by a filter, which filters fluid flowing from the inlet to the outlet. In addition, a re-circulating cover is provided to separate fluid returning through the inlet port from the fluid in the main reservoir chamber. A re-circulating cover is provided that defines a re-circulating chamber. Fluid communication between the main reservoir chamber and the re-circulating chamber is restricted by the re-circulating cover until the main reservoir fluid reaches a predetermined temperature threshold. Accordingly, a given quantity of fluid is re-circulated from the inlet port to the outlet port and is continuously warmed before mixing with main reservoir fluid. Such a reservoir design helps to eliminate cold start up noises.
