Abstract
The utility model discloses a filter supporting spring, including shell, filter core, relief valve and spring, spring coupling is between the interior bottom surface of the bottom of filter core and shell to be located the below of relief valve, the internal diameter of spring is reduced to position among them by its both ends gradually, and spring inside forms big, the middle little space that overflows in both ends. The utility model discloses simple structure, the internal diameter that plays the spring that supports the filter core effect is reduced to position among them by its both ends gradually, and for the diameter -variable structure, under the spring height condition the same with the line footpath, it overflows the space and wants greatly much than current non - reducing supporting spring's the space that overflows.
Description
Technical field
The utility model relates to oil filter field, specifically a kind of cleaner support spring.
Background technology
The support spring installed in oil filter plays the effect of support machine filter element; Spring will have certain space to allow machine oil pass through, in order to avoid safety valve is ineffective, what existing oil filter adopted mostly is non-reducing support spring, and its shortcoming was that fluid space was restricted.
Utility model content
The purpose of this utility model be in order to overcome prior art exist defect and deficiency, a kind of cleaner support spring is provided.
The technical solution of the utility model is as follows:
A kind of cleaner support spring, include shell, filter core, safety valve and spring, described spring is connected between the bottom of described filter core and the inner bottom surface of described shell, and be positioned at the below of described safety valve, it is characterized in that: the internal diameter of described spring by its two ends wherein between position reduce gradually, the formation two ends, inside of spring are large, middlely little cross fluid space.
Described cleaner support spring, is characterized in that: the two ends of described spring are installed in the draw-in groove on the draw-in groove of described filter core bottom and described shell inner bottom surface respectively.
The beneficial effects of the utility model:
The utility model structure is simple, the internal diameter playing the spring supporting filter core effect by its two ends wherein between position reduce gradually, for reducing type structure, when spring heights is identical with wire diameter, it is more much bigger than the mistake fluid space of existing non-reducing support spring that it crosses fluid space.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of support spring in Fig. 1.
Detailed description of the invention
See Fig. 1,2, a kind of cleaner support spring, include shell 1, filter core 2, safety valve 3 and spring 4, spring 4 is connected between the bottom of filter core 2 and the inner bottom surface of shell 1, and be positioned at the below of safety valve 3, the internal diameter of spring 4 by its two ends wherein between position reduce gradually, the formation two ends, inside of spring 4 are large, middlely little cross fluid space 5.
In the utility model, the two ends of spring 4 are installed in the draw-in groove on the draw-in groove of filter core 2 bottom and shell 1 inner bottom surface respectively, mount and dismount all very convenient.
Claims (2)
1. a cleaner support spring, include shell, filter core, safety valve and spring, described spring is connected between the bottom of described filter core and the inner bottom surface of described shell, and be positioned at the below of described safety valve, it is characterized in that: the internal diameter of described spring by its two ends wherein between position reduce gradually, the formation two ends, inside of spring are large, middlely little cross fluid space.
2. cleaner support spring according to claim 1, is characterized in that: the two ends of described spring are installed in the draw-in groove on the draw-in groove of described filter core bottom and described shell inner bottom surface respectively.
