Abstract
The invention discloses a linear boost pressure controller. The linear boost pressure controller comprises a valve body assembly and a valve shaft assembly, wherein a magnetic conducting bracket used for fixing a coil and a magnetic conducting fixing frame are arranged in the valve body assembly; the valve shaft assembly comprises a valve shaft with a step; the magnetic conducting bracket is in thread match with the outer edge of the step of the valve shaft; the whole body of the valve shaft is a smooth shaft; and a valve shaft inner hexagonal angle is arranged at the outer end of the valve shaft. According to the invention, through the matched threads machined on the magnetic conducting bracket and the step of the valve shaft, the distance between the valve shaft and a moving valve core can be adjusted through the valve shaft inner hexagonal angle, so that a purpose of linearly adjusting the boost pressure controller is achieved and the generality of the linear boost pressure controller is further improved.
Description
Technical field
The present invention relates to technical field of engines, particularly the power unit of control 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 so that 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 the motion spool.Coil is arranged in the valve body by magnetic conduction support and the magnetic conduction fixing frame that is fixedly installed on the valve body assembly, and the valve shaft assembly is fixed together by even fixedly hangnail and the coil inwall of cloth on valve shaft.When coil get by contact pin electric after so that valve shaft produces magnetic, thus adhesive campaign spool, the suction-combining force acts on mutually with Returnning spring power, so that the air pressure of output changes, the ECU control inputs is to the dutycycle of charging-pressure adjusting device, thus so that 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 present invention solves provides a kind of charging-pressure adjusting device of linear adjustment, to improve versatility of the present invention.
For solving the problems of the technologies described above, the technical solution used in the present invention 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 the 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 the valve shaft.
Improvement of the present invention is: the end face that described valve shaft contacts with the coil inwall is even to be furnished with at least one annular groove, is embedded with the seal ring with coil inwall interference fit in the groove.
Owing to adopted above technological scheme, the invention technological progress is:
The present invention is by processing the screw thread that cooperatively interacts at magnetic conduction support and valve shaft step, can be by the distance between hexagonal adjusting valve shaft and the motion spool in the valve shaft, thereby reach the purpose that realizes the charging-pressure adjusting device linearly adjust, further improve versatility of the present invention.Seal ring in the groove that arranges on the valve shaft and the groove has improved the sealability between valve shaft assembly and the coil greatly, prevents that extraneous gas from flowing in the valve body.

Below in conjunction with the drawings and specific embodiments the present invention 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 the valve body by magnetic conduction support 6 and magnetic conduction fixing frame 2.The valve shaft assembly is sleeved in the 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 the motion spool, is used for the reseting movement spool.
The inner ring of magnetic conduction support 6 is provided with screw thread among the present invention, 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 the valve shaft.The end face that valve shaft contacts with the coil inwall is even to be furnished with at least one annular groove, is embedded with the seal ring 53 with coil inwall interference fit in the groove.As shown in Figure 2.
When the present invention assembles, 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 the 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 shafts and the motion spool by hexagonal in the valve shaft 52 again, thereby so that the performance linearity of charging-pressure adjusting device change.
