    • A fluid heating system for a work vehicle includes a pressurized fluid circuit having a pump for providing pressurized fluid to the fluid circuit. A control module for controlling a first control device is in fluid communication with the fluid circuit, the first control device operable between a first position and a second position. The first position of the first control device permits a load sense pressure to be applied through the first control device, thereby preventing pressurized fluid from the pump flowing to a pressure return tank for heating the pressurized fluid. The second position of the first control device prevents the load sense pressure from being applied through the first control device, thereby permitting pressurized fluid from the pump flowing to a pressure return tank and resulting in heating of pressurized fluid of the fluid circuit.
    • 用于工作车辆的流体加热系统包括具有用于向流体回路提供加压流体的泵的加压流体回路。 用于控制第一控制装置的控制模块与流体回路流体连通,第一控制装置可在第一位置和第二位置之间操作。 第一控制装置的第一位置允许通过第一控制装置施加载荷感测压力,从而防止来自泵的加压流体流向加压回流罐,以加热加压流体。 第一控制装置的第二位置防止负载感测压力通过第一控制装置施加,从而允许来自泵的加压流体流向压力回流罐并导致流体回路的加压流体的加热。
