Filler assembly of engine cooling system

Abstract

The invention discloses a filler assembly of an engine cooling system. The filler assembly comprises a water storage tank and a filling device, wherein the water storage tank is used for storing cooling liquid. A body of a hollow structure is provided with a water supplementing inlet, an exhaust port and a siphoning mouth, a control cavity is formed in the hollow cavity, the water supplementing inlet is communicated with a water supplementing loop in the engine cooling system, the exhaust port is communicated with an exhaust loop, and the siphoning mouth is communicated with the water storage tank. A pressure cap is fixedly arranged on the body, a siphon spring for controlling water supplementing of the system and a drainage spring for controlling drainage of the system are arranged in the pressure cap, the siphon spring and the drainage spring are arranged in the control cavity, and the siphoning mouth is communicated with the control cavity. The filler assembly of the engine cooling system has the advantages that with the filling device and the water storage tank, the filler assembly meets the requirements on supplementing of the cooling liquid and pressure regulation in the system and can be used for different models of vehicles universally.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an engine cooling system filling port assembly. Background technique [0002] The expansion kettle is an important part in the engine cooling system to replenish the coolant that is continuously consumed and to regulate the system pressure. [0003] In the prior art, the structure of the expansion kettle often needs to be designed according to the structure of the car. Due to the difference in the structure and layout space of the car, the structural shape of the expansion kettle is different, which increases the development cost and development cycle of the expansion kettle. It also makes the expansion kettle not universal. Contents of the invention [0004] The purpose of the present invention is to provide an engine cooling system filling port assembly, so as to realize the function of the expansion kettle in the above-mentioned prior art, and at the same time satisfy t...
