Abstract: A tank for a hydraulic fluid has a housing with opposed end walls and side walls defining an interior chamber. A primary baffle is disposed inside the housing and divides the interior chamber into an inlet chamber and an outlet chamber, with a primary gap between the primary baffle and the housing fluidly communicating between the inlet chamber and the outlet chamber. The primary baffle further defines a contact surface facing the inlet chamber and has first and second weirs which extend into the inlet chamber. A first fluid inlet fluidly communicates with the inlet chamber and is oriented along a first inlet axis that intersects the contact surface, while a fluid outlet communicates with the outlet chamber. The tank produces an interior flow that mixes and deaerates the fluid as it travels from the first fluid inlet to the fluid outlet.

Abstract: A skid steer type machine is equipped with an overheat protection algorithm that keeps the machine productive even when the hydraulic system is in an overheated condition. When an elevated hydraulic fluid temperature is detected, an electronic controller derates a pump of the hydraulic system to limit pump output to a reduced flow rate down from a rated flow rate. The hydraulic fluid tends to cool down when the pump is derated, but the machine remains productive while the hydraulic system is cooling down.
