The utility model further is set to: between described refill lower cover and housing bottom, be provided with damping spring.
By adopting technique scheme, damping spring can avoid the violent oil-feed section of rocking and screw thread oil outlet joint to apply excessive pressure so that refill is cushioned when being subject to Oil shocking, has prevented that the distortion of screw thread oil outlet from producing gap.
The utility model further is set to: between the joint of described oil-feed section and fuel-displaced section and refill upper cover, be provided with for sealing the interior confidential paper of oil outlet and refill upper cover.
By adopting technique scheme, make excellent sealing between oil outlet and refill upper cover, prevent that the oil leakage at screw thread oil outlet place is to the filler opening place.
The utility model further is set to: the plat part of described thread plate is provided with the fixing sealing plate of butt-joint on an end end face of refill upper cover dorsad, and the outer rim of sealing plate is provided with the flanging part be fixedly connected with housing.
By adopting technique scheme, described sealing plate can closely be connected thread plate with housing, simple in structure, easy to process.
The beneficial effects of the utility model are: owing to taking technique scheme, thread plate is the setting of dish shape and oil-feed section to center tube depression and is to the cambered surface of refill upper cover projection towards the face of refill upper cover one side, make thread plate there is the pressure that higher intensity can be born larger machine oil, therefore, thereby thread plate is difficult for distortion under the engine oil pressure effect, in generation gap, oil outlet place, effectively prevents the gap leakage that machine oil produces from distortion.
Equally distributed filler opening makes the pressure that thread plate is subject to be uniformly distributed, avoided unbalance stress and made the part generation deformation at maximum weighted point place, and the joint of oil-feed section and fuel-displaced section is provided with fillet, the joint of arc arranges the further compressive resistance ability of having strengthened this joint.And be provided with damping spring between refill lower cover and housing bottom, make refill be cushioned when being subject to the machine oil impact, avoided the violent joint of rocking oil-feed section and fuel-displaced section to apply excessive pressure, prevented that the oil outlet distortion from producing gap, service behaviour and the working life of having improved oil filter.
Be provided with interior confidential paper between the joint of described oil-feed section and fuel-displaced section and refill upper cover, make oil outlet and refill upper cover excellent sealing, prevent that the oil leakage at oil outlet place is to the filler opening place.
By the sealing plate, thread plate closely can be connected with housing, simple in structure, easy to process.
