Abstract
The utility model discloses a linear supercharging pressure controller which comprises a valve body assembly and a valve shaft assembly, wherein a magnetic conduction support and a magnetic conduction fixed bracket, which are used for fixing a coil, are arranged in the valve body assembly, the valve shaft assembly comprises a valve shaft with a step, the outer edge of the magnetic conduction support is in threaded fit with the outer edge of the step of the valve shaft, the entire body of the valve shaft is a smooth shaft, and the outer end of the valve shaft is provided with a valve shaft inner hexagon. The magnetic conduction support and the step of the valve shaft are respectively provided with the threads matched with each other, and the distance between the valve shaft and a movable valve core can be adjusted through the valve shaft inner hexagon, thereby realizing the linear adjustment purpose of the supercharging pressure controller and further improving the universality of the linear supercharging pressure controller.
Description
Technical field
The utility model relates to technical field of engines, particularly controls the power unit of pressurized machine two-stage supercharging on a kind of motor.
Background technique
Pressurized machine is to utilize the inertia impulsive force of the waste gas that motor discharges to promote turbine, the turbine impeller, and the air that the impeller force feed is sent here by the air-strainer pipeline enters cylinder after making supercharging air.The working principle of charging-pressure adjusting device is by inputting different dutycycles, make the solenoid valve of the linear variation of gas pipeline internal pressure differences, charging-pressure adjusting device the good normal use of having protected other sensors is set.
Charging-pressure adjusting device commonly used comprises valve body assembly and is arranged on valve body assembly interior motion spool and valve shaft assembly at present, is provided with Returnning spring between valve shaft assembly and motion spool.Coil is arranged in valve body by magnetic conduction support and the magnetic conduction fixing frame that is fixedly installed on valve body assembly, and the fixedly hangnail on valve shaft and coil inwall are fixed together the valve shaft assembly by even cloth.When coil get by contact pin electric after, make valve shaft produce magnetic, thus adhesive campaign spool, the suction-combining force acts on mutually with Returnning spring power, make the air pressure of output change, the ECU control inputs is to the dutycycle of charging-pressure adjusting device, thereby makes the air pressure generation linear change of output.Yet because the inner ring of coil and valve shaft are to be fixed together by fixing hangnail, in case after therefore valve shaft was fitted into valve body assembly, the position of valve shaft and coil namely was fixed as one, and can not regulate its linear change, thereby limited the application of charging-pressure adjusting device, narrow limitation is larger.
Summary of the invention
But the technical problem that the utility model solves is to provide a kind of charging-pressure adjusting device of linear adjustment, to improve versatility of the present utility model.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Linear charging-pressure adjusting device, comprise valve body assembly and valve shaft assembly, be provided with magnetic conduction support and magnetic conduction fixing frame for fixed coil in valve body assembly, the valve shaft assembly comprises valve shaft with the level, the outer screw-thread fit of described magnetic conduction support and valve shaft step, described valve shaft entire body is smooth shaft, and the outer end of valve shaft is provided with hexagonal in valve shaft.
Improvement of the present utility model is: even at least one annular groove that is furnished with of the end face that described valve shaft contacts with the coil inwall is embedded with the seal ring with coil inwall interference fit in groove.
Owing to having adopted above technological scheme, the obtained technological progress of the utility model is:
The utility model is by processing the screw thread that cooperatively interacts on magnetic conduction support and valve shaft step, can be by the distance between hexagonal adjusting valve shaft and motion spool in valve shaft, thereby reach the purpose that realizes the charging-pressure adjusting device linearly adjust, further improve versatility of the present utility model.Seal ring in the groove that arranges on valve shaft and groove has improved the sealability between valve shaft assembly and coil greatly, prevents that extraneous gas from flowing in valve body.

Fig. 2 is the structural representation of described valve shaft.
Wherein: 1. coil connectors, 2. magnetic conduction fixing frame, 3. coil, 4. valve body, 5. valve shaft, hexagonal in 51. valve shaft steps, 52. valve shafts, 53. seal rings, 54. copper pipes, 6. magnetic conduction support, 7. Returnning spring, 8. motion spool.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
A kind of linear charging-pressure adjusting device, its structure as shown in Figure 1.Comprise valve body assembly and valve shaft assembly, valve body assembly comprises valve body 4, coil 3, magnetic conduction fixing frame 2, magnetic conduction support 6 and coil connectors 1, and coil 3 is arranged in valve body by magnetic conduction support 6 and magnetic conduction fixing frame 2.The valve shaft assembly is sleeved in valve body assembly, comprise valve shaft 5 with the level, motion spool 8 and Returnning spring 7, the motion spool is positioned at the coil connectors side of valve body, and valve shaft is arranged in the coil inwall, Returnning spring 7 connects between valve shaft and motion spool, is used for the reseting movement spool.
In the utility model, the inner ring of magnetic conduction support 6 is provided with screw thread, and the outer of valve shaft step 51 also is provided with screw thread, and the magnetic conduction support is corresponding with valve shaft step position, and passes through screw-thread fit.Described valve shaft entire body is smooth shaft, and the outer end of valve shaft is provided with hexagonal 52 in valve shaft.Even at least one annular groove that is furnished with of the end face that valve shaft contacts with the coil inwall is embedded with the seal ring 53 with coil inwall interference fit in groove.As shown in Figure 2.
During the utility model assembling, at first motion spool 8 is put into valve body assembly, then place Returnning spring, at last by with valve body assembly in screw thread cooperatively interacts on magnetic conduction support 6 valve shaft step 51 will be fixed together with valve shaft assembly and the valve body assembly of seal ring 53, the distance of regulating between valve shaft and motion spool by hexagonal in valve shaft 52 again, thus make the performance linearity of charging-pressure adjusting device change.
