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 the diesel engine technologies field, concrete 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 cooperates spring, need to be the accurate design and installation of ball valve position in oil filter seating inside, and offer the bypass oil duct, increased manufacture difficulty and the cost of oil filter seating mould.Because the bulk of ball valve mounting point is not enough, easily produce the dead band in the engine oil flow process simultaneously, repeatedly occur in the using process to open unusual or bypass valve stuck phenomenon by the bypass valve that causes from other position impurity of motor.
Summary of the invention
The objective of the invention is to provide a kind of compact structure, rationally distributed, and strong adaptability has been optimized the engine oil filter by-pass valve assembly of the internal structure of oil filter seating.
For achieving the above object, the engine oil filter by-pass valve assembly that the present invention is designed, 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 along being circumferentially with annular cover plate, described valve rod lower end edge is circumferentially with circular end surface, described valve rod is positioned at the first central through bore, and described circular end surface is covered in the lower end mouth of the first central through bore; The two ends that described spring housing is connected to valve rod outer wall and spring are fixedly connected with the inwall of valve rod with the tubular valve gap respectively.
As preferred version, described valve gap top also is 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 the first central through bore and the second central through bore communicate, and the upper edge of described engagement portion is provided with the annular barb groove.
Further, the inwall lower end of described the first central through bore is provided with annular slot, and an 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: the valve rod of this by-pass valve assembly and valve gap all adopt engineering plastics, can carry out diversified design to its structure according to the actual requirements, and be flexible.The by-pass valve assembly overhead in oil filter seating, is both rationally utilized the space resources between cover assembly and the filter core assembly, avoided again the complicated processing of prior art to oil filter seating; Utilize simultaneously the annular projection design of valve gap, after sale more back out cover assembly during renew cartridge in oil filter and can take in the lump filter core out of, simplify the operation, convenient and easy.

Fig. 3 is that A-A of Fig. 2 illustrates to cross-section structure.
Fig. 4 is blast structural representation of the present invention.
Among the figure: valve rod 1, top hook groove 1.1, circular end surface 1.2, valve gap 2, annular slot 2.1, annular cover plate 2.2, annular projection 2.3, annular barb groove 2.4, the first central through bores 2.5, engagement portion 2.6, the second central through bores 2.7, spring 3.
Embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
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, the valve gap top is along being circumferentially with annular cover plate 2.2, valve rod 1 lower end edge is circumferentially with circular end surface 1.2, valve rod 1 is positioned at the first central through bore 2.5, and circular end surface 1.2 is covered in the lower end mouth of the first central through bore 2.5; The two ends that spring 3 is socketed on valve rod 1 outer wall and spring 3 are fixedly connected with the inwall of valve rod 1 with tubular valve gap 2 respectively.
Above-mentioned valve gap 2 tops also are provided with the engagement portion 2.6 of annular, and engagement portion 2.6 is provided with coaxial the second central through bore 2.7, the first central through bores 2.5 and the second central through bore 2.7 of the first central through bore 2.5 and 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 an 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 the top hook groove 1.1; Valve gap 2 outer walls are 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: the machine oil that enters in bypass valve valve gap 2 chambeies produces pressure to the circular end surface 1.2 of valve rod 1, when the engine oil pressure rising reaches setting value, machine oil backs down the circular end surface 1.2 of valve rod 1, spring 3 produces compression displacement, machine oil is thereupon by by-pass valve assembly, and the purpose of oil circuit engine oil pressure in the oil filter chamber is regulated in final realization.
Valve rod 1 is inserted in the bypass valve valve gap 2, and spring 3 one ends are spacing with the annular slot 2.1 of described valve gap 2, and an end is clamped in the top hook groove 1.1 of valve rod 1, thereby realizes being fixedly connected with of three parts.Utilize unlatching and the aperture of the elastic stiffness control valve of spring 3 during by-pass valve assembly work.During correct the installation, by-pass valve assembly directly is pressed into the filter core center tube to the annular cover plate 2.2 and the complete applying compression of filter core engagement portion felt face of bypass valve valve gap 2, then according to standard tightening machine oil rectifier cap assembly is installed and is got final product.When maintaining after sale, utilize annular projection 2.3 on the valve gap 2 and the structural design of annular barb groove 2.4, back out cover assembly and can take in the lump filter core out of, make that more renew cartridge is more convenient.
