Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.It will be appreciated that, mentioned in the following mode of execution of the present utility model " on ", D score, " left side ", " right side ", " front " and " reverse side " be benchmark with the direction shown in each figure all, these words that are used for limiting direction only are for convenience of explanation, do not represent the restriction to the concrete technological scheme of the utility model.
Hydraulic injection pump oil controller of the present utility model is located in camshaft in the oil mass limiting stopper by rotation, utilize camshaft overhead cam radius of arc center location difference that the lateral attitude that the axial rotation of camshaft is converted into the oil mass limiting stopper is moved, and then adjust the Injection Pump oil mass according to the actual job operating mode.
As shown in Figure 1, the concrete structure of this hydraulic injection pump oil controller comprises: cover plate 1, camshaft 2, supporting sleeve 3, oil mass limiting stopper 4 and holddown spring 5, wherein, cover plate 1 and supporting sleeve 3 are from 2 rotations of two end supports camshaft, oil mass limiting stopper 4 is located on the camshaft 2, and slidably is arranged on the supporting sleeve 3.
The transverse slat of cover plate 1 offers coaxial oil sealing counterbore and camshaft perforation from top to bottom successively.During assembling, oil sealing 11 is installed in the oil sealing counterbore, is made the non-leakage and dustproof effect of machine oil in the oil pump, the degree of depth of oil sealing counterbore and diameter are according to the size design of standard oil sealing; The camshaft perforation is unthreaded hole, play the effect of supporting cam wheel axle upper half part, the big 0.04-0.1mm of its shaft diameter than camshaft 2, the diameter of the axostylus axostyle of camshaft 2 is fixed according to the interior hole dimension of oil sealing 11, it is good with employing outside framework oil seal being arranged, and concrete specification is selected with reference to the countries concerned's standard.
