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.

Abstract

The invention belongs to the field of aviation lubricating oil systems, and relates to a multifunctional valve assembly for a pump. According to the valve assembly, an anti-siphon valve, a bypass valve and a cut-off valve share one anti-siphon valve body, the bypass valve and the cut-off valve share one spring and the cut-off valve body, a corresponding structure is arranged in a pump shell to fix and limit the valve assembly, and a limiting body is connected with a left oil pipeline; when the oil pipeline is disassembled, the limiting body can be disassembled together with the oil pipeline; the cut-off valve makes contact with a sealing retainer under the action of a first spring, the sealing gasket is compressed, so that oil leakage is prevented; the valve assembly is limited through the limiting body when the pipeline is connected with the pump; and all moving parts of the valve assembly move by proper opening degrees according to the pressure of lubricating oil in a working cavity, and therefore, the functions of the bypass valve and the anti-siphon valve are realized. The valve assembly is high in integration level, small in size and light in weight.

Description

technical field [0001] The invention belongs to the technical field of aviation lubricating oil systems, and in particular relates to a multifunctional valve assembly for a pump. Background technique [0002] Under normal circumstances, anti-siphon valves, bypass valves, cut-off valves and other valve structures are often installed separately in aviation lubricating oil systems, generally composed of valve cores, valve sleeves, springs, valve seats, etc. Relatively many, taking up a lot of space, when matching with pump products, a special oil circuit needs to be set up, resulting in many accessories of the lubricating oil system and complicated system piping, which is not conducive to weight reduction and improvement of engine power-to-weight ratio. Contents of the invention [0003] The purpose of the present invention is to design a multifunctional valve assembly for a pump to solve the technical problems of the complexity of the current aviation oil system and the redu...
