In this embodiment, the temperature control assembly includes a temperature control valve sleeve slidably mounted in the valve body, a temperature control valve core 22 disposed on the temperature control valve sleeve, and a temperature control spring 21 mounted in the valve body for adjusting the position of the temperature control valve core, where the temperature control valve sleeve can slide along the axial direction of the oil return channel and drive the temperature control valve core to open or close the oil return channel. The temperature control valve sleeve is integrally in a tubular structure, is arranged in the oil return channel and can axially slide along the channel after being controlled by a temperature sensing device (the temperature sensing device is in the prior art and is not described in detail).
In this embodiment, the cold oil outlet c is communicated with the oil return channel, and the temperature control valve sleeve is provided with a valve sleeve opening 24, and the valve sleeve opening 24 is used for guiding oil to the cold oil outlet. When the temperature control valve core 22 runs leftwards in fig. 1, the channel opening of the temperature control valve core can be closed, the corresponding temperature control valve sleeve also moves leftwards, and the valve sleeve opening 24 is also in a closed state at the moment, so that the effect of twice sealing is realized.
