THERMOREGULATOR

摘要

A thermostatic valve includes a housing internally provided with a receiving cavity and a thermostatic actuating element mounted in the receiving cavity. The receiving cavity is in communication with the exterior through at least three ports such as a first connecting port, a second connecting port, and a third connecting port. The thermostatic actuating element is mounted in the housing via two elastic members. An annular sealing collar which is fixedly mounted is provided in the receiving cavity. At least most of the thermostatic actuating element is located between the third port and the sealing collar. Such arrangement may ensure the temperature of the transmission oil when having a low temperature can rise rapidly and ensure the lubrication performance of a transmission. In addition, a processing precision requirement for components and parts can be reduced and manufacturing and mounting are more convenient

1. A thermostatic valve, comprising a housing in which an receiving cavity is provided, and a thermostatic actuating element mounted in the receiving cavity, wherein the receiving cavity is in communication with an outside through at least three connecting ports comprising a first connecting port, a second connecting port and a third connecting port; the thermostatic actuating element comprises a main body of the thermostatic actuating element in which a thermosensitive substance is provided, and the thermostatic actuating element is mounted in the receiving cavity of the housing via two elastic members; and an annular sealing collar which is fixedly mounted is provided in the receiving cavity, and the first connecting port and the second connecting port are located at two sides of the sealing collar, respectively;
a first passage is formed in a case that the second connecting port, an inner hole of the sealing collar and the first connecting port are in communication with each other, and a second passage is formed in a case that the first connecting port and the third connecting port are in communication with each other; in a case that a fluid has a low temperature, the thermosensitive substance in the thermostatic actuating element contracts, the main body of the thermostatic actuating element is moved towards the sealing collar under the action of an elastic force of the respective elastic member, which enables a second engaging portion of the main body of the thermostatic actuating element or a second engaging portion fixedly provided on the main body of the thermostatic actuating element to abut against the sealing collar or cover the inner hole of the sealing collar, to block the first passage and open the second passage; and in a case that the fluid has a high temperature, the thermosensitive substance in the thermostatic actuating element expands, the main body of the thermostatic actuating elements moves towards the third connecting port, until a first engaging portion of the main body of the thermostatic actuating element or a first engaging portion fixedly provided on the main body of the thermostatic actuating element abuts against an end surface of a part of the housing where the third connecting port is located or covers the third connecting port, to block the second passage and open the first passage.
