Embodiment Construction
[0028] The multifunctional valve assembly for pumps of the present invention highly integrates the functions of various valves in pump products. By sharing an anti-siphon valve body with the bypass valve and the cut-off valve, the bypass valve and the cut-off valve The same spring and cut-off valve body are used. The corresponding structure is set in the pump housing to fix and limit the valve assembly. The limit body is connected to the left oil pipeline. When the oil pipeline is disassembled, the limit body is disassembled together. Next, the cut-off valve is in contact with the sealing retainer under the action of the first spring, and the sealing gasket is compressed to prevent oil leakage. Each moving part of the assembly moves an appropriate opening degree, thereby realizing the function of the bypass valve and the anti-siphon valve.
[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
