Abstract
The invention discloses a bypass valve assembly for an engine oil filter, which comprises a cylindrical valve cover provided with a first central through hole, a valve rod and a spring, and is characterized in that: the top of the valve cover is circumferentially provided with an annular cover plate, the lower end of the valve rod is circumferentially provided with a circular end face, the valve rod is positioned in the first central through hole, and the circular end face covers the lower port of the first central through hole; the spring is sleeved on the outer wall of the valve rod, and two ends of the spring are fixedly connected with the valve rod and the inner wall of the cylindrical valve cover respectively. The bypass valve assembly is arranged in the oil filter support in an overhead mode, so that space resources between the filter cover assembly and the filter element assembly are reasonably utilized, and complex processing of the oil filter support in the prior art is avoided. Meanwhile, the convex barb design of the valve cover of the bypass valve is utilized, and the filter element can be taken out together by unscrewing the filter cover assembly when the filter element is replaced after the oil filter is sold, so that the operation is simplified, and the filter is convenient and easy to operate.
Description
Technical field
The present invention relates to diesel engine technologies field, particularly refer to a kind of engine oil filter by-pass valve assembly.
Background technique
There is following drawback in certain existing light-duty diesel engine oil filter bypass valve: structure is the ball-valve structure that traditional steel ball coordinates spring, needing in oil filter seating inside is ball valve careful design mounting point, and offer bypass oil duct, add manufacture difficulty and the cost of oil filter seating mould.Bulk simultaneously due to ball valve mounting point is not enough, easily produces dead band in engine oil flow process, repeatedly occurs to open exception or bypass valve stuck phenomenon by the bypass valve caused from other position impurity of motor in using process.
Summary of the invention
The object of the invention is to provide a kind of compact structure, rationally distributed, strong adaptability, optimizes the engine oil filter by-pass valve assembly of the internal structure of oil filter seating.
For achieving the above object, engine oil filter by-pass valve assembly designed by the present invention, comprise the tubular valve gap, valve rod and the spring that are provided with the first central through bore, its special way is: described valve gap top is circumferentially provided with annular cover plate, described valve rod lower end edge is circumferentially with circular end face, described valve rod is positioned at the first central through bore, and described circular end face is covered in the lower end mouth of the first central through bore; Described spring housing is connected to valve rod outer wall and the two ends of spring are fixedly connected with the inwall of valve rod with tubular valve gap respectively.
Preferably, described valve gap top is also provided with the engagement portion of annular, and described engagement portion is provided with second central through bore coaxial with the first central through bore, and described first central through bore and the second central through bore communicate, and the upper edge of described engagement portion is provided with annular barb groove.
Further, the inwall lower end of described first central through bore is provided with annular slot, and one end of described spring is fixedly connected with annular slot.
Further, described valve rod upper end is provided with top hook groove, and the other end of described spring is clamped in the hook groove of top.
Further, described valve gap outer wall is provided with annular projection.
Further, the material of described valve rod and valve gap is engineering plastics.
The invention has the advantages that: valve rod and the valve gap of this by-pass valve assembly all adopt engineering plastics, diversified design can be carried out to its structure according to the actual requirements, flexibly and easily.By by-pass valve assembly overhead in oil filter seating, both the space resources of Appropriate application between cover assembly and filter core assembly, turn avoid the complicated processing of prior art to oil filter seating; Utilize the annular projection of valve gap to design simultaneously, oil filter after sale more renew cartridge time back out cover assembly and can take filter core out of in the lump, simplify the operation, convenient and easy.

In figure: valve rod 1, top hook groove 1.1, circular end face 1.2, valve gap 2, annular slot 2.1, annular cover plate 2.2, annular projection 2.3, annular barb groove 2.4, first central through bore 2.5, engagement portion 2.6, the second central through bore 2.7, spring 3.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Engine oil filter by-pass valve assembly shown in Fig. 1, comprise the tubular valve gap 2, valve rod 1 and the spring 3 that are provided with the first central through bore 2.5, valve gap top is circumferentially provided with annular cover plate 2.2, valve rod 1 lower end edge is circumferentially with circular end face 1.2, valve rod 1 is positioned at the first central through bore 2.5, and circular end face 1.2 is covered in the lower end mouth of the first central through bore 2.5; Spring 3 is socketed on valve rod 1 outer wall and the two ends of spring 3 are fixedly connected with the inwall of valve rod 1 with tubular valve gap 2 respectively.
Above-mentioned valve gap 2 top is also provided with the engagement portion 2.6 of annular, and engagement portion 2.6 is provided with second central through bore 2.7, first central through bore 2.5 coaxial with the first central through bore 2.5 and the second central through bore 2.7 communicates, and the upper edge of engagement portion 2.6 is provided with annular barb groove 2.4; The inwall lower end of the first central through bore 2.5 is provided with annular slot 2.1, and one end of spring 3 is fixedly connected with annular slot 2.1; Valve rod 1 upper end is provided with top hook groove 1.1, and the other end of spring 3 is clamped in top hook groove 1.1; Valve gap 2 outer wall is provided with annular projection 2.3.
The material of above-mentioned valve rod 1 and valve gap 2 is engineering plastics.
Working principle of the present invention is as follows: enter the circular end face 1.2 of the machine oil in bypass valve valve gap 2 chamber to valve rod 1 and produce pressure, when engine oil pressure rising reaches setting value, machine oil backs down the circular end face 1.2 of valve rod 1, spring 3 produces compression displacement, machine oil by by-pass valve assembly, finally realizes the object of oil circuit engine oil pressure in conditioner oil rectifier chamber thereupon.
Valve rod 1 is inserted in bypass valve valve gap 2, and spring 3 one end is spacing with the annular slot 2.1 of described valve gap 2, and one end is clamped in the top hook groove 1.1 of valve rod 1, thus realizes being fixedly connected with of three parts.Unlatching and the aperture of the elastic stiffness control valve of spring 3 is utilized during by-pass valve assembly work.During correct installation, by-pass valve assembly is directly pressed into filter core center tube to the annular cover plate 2.2 of bypass valve valve gap 2 and compresses with complete laminating the in felt face, filter core engagement portion, then according to specification installation tightening machine oil rectifier cap assembly.When maintaining after sale, utilize the structural design of annular projection 2.3 on valve gap 2 and annular barb groove 2.4, back out cover assembly and can take filter core out of in the lump, make more renew cartridge more convenient.
