Oil temperature control bypass valve and engine with same

The invention discloses an oil temperature control bypass valve which comprises a shell (1), an upper guide sleeve (2), a lower guide sleeve (4) and a temperature control push rod component. An oil inlet is formed in the lower end of the shell (1), a first oil outlet (1-1), a second oil outlet (1-2) and a third oil outlet (1-3) are axially formed in the side wall of the shell (1), a fourth oil outlet (1-4) is formed in the upper end of the shell (1), the upper guide sleeve (2) is provided with an upper spring (3), the lower end of the upper guide sleeve (2) is sealed and positioned between the first oil outlet (1-1) and the second oil outlet (1-2), a conduction oil port (2-1) is formed in the side wall of the upper guide sleeve (2), the lower guide sleeve (4) is provided with a lower spring (5), the rigidity of the upper spring (3) is higher than that of the lower spring (5), and a push rod (7) of the temperature control push rod component supports the lower guide sleeve (4). An oil temperature control valve and an oil bypass valve are organically integrated by the oil temperature control bypass valve, the oil trend can be effectively switched over, the oil temperature is controlled, the oil temperature control bypass valve has bypass and pressure limiting functions and is compact in structure, small in size and light in weight, and arrangement of an engine and weight reduction of parts are facilitated.
