    • A lubrication system thermostat for controlling the flow of oil in a lubrication system includes a valve and an actuator. The valve is configured to modulate between an unmodulated position and a modulated position, each of which may be in an open position or a closed position. In the open position, at least a portion of the oil flow is unobstructed, and in the closed position, the oil flow is substantially blocked. The actuator is configured to modulate the valve. The actuator includes a thermal element configured to generate mechanical displacement when subjected to a temperature change such that the valve is movable from and returnable to the unmodulated position. The lubrication system thermostat may be in a normally-open configuration, in which the unmodulated position is the open position, or a normally-closed configuration, in which the unmodulated position is the closed position.
    • 用于控制润滑系统中的油流的润滑系统恒温器包括阀和致动器。 阀构造成在未调节位置和调制位置之间进行调制,每个位置可处于打开位置或关闭位置。 在打开位置,油流的至少一部分是畅通无阻的,并且在关闭位置,油流被基本阻挡。 致动器被配置成调节阀门。 致动器包括热元件,该热元件构造成当经受温度变化时产生机械位移,使得阀可移动并且可返回到未调制位置。 润滑系统恒温器可以处于常开状态,其中未调节位置是打开位置,或常闭形式,其中未调节位置处于关闭位置。
