Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1 to Fig. 4, the device preventing camshaft-signal sensor to lose efficacy being applied to the high pressure oil pump of fuel injection system provided in figure, comprises the pump housing 1, cam 14, signal panel 10, camshaft-signal sensor 18 and a camshaft-signal sensor protective gear.
One end of camshaft 14 supports by bearing 13 and bearing cap 15 side being arranged on the pump housing 1, the other end of camshaft 14 supports the opposite side being arranged on the pump housing 1 by bearing 13, signal panel 10 are arranged on the other end of camshaft 14 by screw 16 and pad 17 and are positioned at the outside of bearing 13.These signal panel 10 are for identifying cam sensor 18 signal.
Camshaft-signal sensor protective gear of the present utility model comprises one and adopts pad 3 and screw 4 to be arranged on the pump housing 1 opposite side and camshaft-signal sensor erection support 2 between bearing 13 and signal panel 10; Sealing 12 is configured with between the interior edge face and the outer side surface of the pump housing 1 opposite side of camshaft-signal sensor erection support 2; the configuration mode of Sealing 12 is: on the interior edge face of camshaft-signal sensor erection support 2, be provided with Sealing embed annular groove, Sealing 12 embeds the seal and embeds in annular groove.Prevent the installation because of camshaft-signal sensor erection support 2 from causing oil leakage to arrive the outside of the pump housing 1 by Sealing 12, signal panel 10 and camshaft-signal sensor 18 are polluted, affects their measuring accuracy.
