Detailed description of the invention
In order to make the technical problem to be solved, technical scheme and beneficial effect clearer, Below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that this place is retouched The specific embodiment stated only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1 and Figure 4, being a preferred embodiment of the present invention, this automobile-used Pneumatic controller includes Main valve 100 between air pump and air accumulator, and the first forced induction valve 200 being positioned on main valve 100 With the second forced induction valve 300.
Main valve 100 includes valve body 110, main valve plug 120, back-moving spring 130 and plunger shaft 140.Valve body 110 Side be provided with for connecting the air accumulator interface 111 of air accumulator and being connected to the air vent 112 of air, its Opposite side is provided with the air pump interface 113 for connecting air pump.Main valve plug 120 is positioned at valve body 110, its table Face is provided with groove 121, forms plunger shaft 140, its other end and valve body 110 between its one end and valve body 110 Between be provided with back-moving spring 130.
First forced induction valve 200 has the first inlet end and the first outlet side (not indicating in figure), and second Forced induction valve has the second inlet end and the second outlet side (not indicating in figure).Main valve 100 is internal to be provided with Pressure passage 114, piston intake passage 115 and exhaust passage 116.One end of pressure passage 114 is connected to Air accumulator interface 111, its other end is connected to the first forced induction valve 200 and the second forced induction valve First inlet end of 300 and the second inlet end.One end of piston intake passage 115 is connected to plunger shaft 140, Its other end is connected to the first forced induction valve 200 and the first outlet side of the second forced induction valve 300 With the second outlet side.Before exhaust passage 116 is positioned at first, second forced induction valve 200,300, one End is connected to piston intake passage 115, and its other end is communicated in air.
Specifically, valve body 110 includes main valve body 1102, and is fixedly arranged on main valve body 1102 two ends respectively Drive end bearing bracket 1101 and rear end cap 1103.It is internal that main valve plug 120 is arranged in main valve body 1102, and its two ends Lay respectively in drive end bearing bracket 1101 and rear end cap 1103.Plunger shaft 140, pressure passage 114 and piston enter Gas passage 115 is all located in drive end bearing bracket 1101, and exhaust passage 116 is arranged in drive end bearing bracket 1101 and main valve body In 1102.
First forced induction valve 200 include first valve body the 210, first spool the 220, first balancing spring 230, With first piston 240.First spool 220 and first piston 240 are all located in the first valve body 210, and First piston 240 is fixedly arranged on below the first spool 220.First inlet end is positioned at below first piston 240, First outlet side is positioned at the side of the first valve body 210.The first spool 220 is located at by first balancing spring 230 Between upper end and the first valve body 210.The pressure of air accumulator is P;When P is < during A, above first piston 240 Gas pressure less than the elastic force of the first balancing spring 230, the first spool 220 is positioned at the initial position of lower section, First inlet end and the connection of the first outlet side, wherein, A is the setting pressure of the first forced induction valve 200; As P >=A, the gas pressure above first piston 240 is more than the elastic force of the first balancing spring 230, the One spool 220 moves upward, and makes the first inlet end and the first outlet side disconnect.In the present embodiment, force value A is 0.6MPa.
Second forced induction valve 300 includes the second valve body the 310, second spool 320 and the second balancing spring 330. Second spool 320 is located in the second valve body 310, and the second inlet end is positioned at below the second valve body 310, and second Outlet side is positioned at the second valve body 310 side.Second balancing spring 330 be located at the upper end of the second spool 320 with Between second valve body 310.When the pressure value P of air accumulator, < during B, the second spool 320 underlying gas pressure is little In the elastic force of the second balancing spring 330, the second spool 320 is positioned at initial position, the second inlet end and second Outlet side disconnects, and wherein, B is the setting pressure of the second forced induction valve 300;As P >=B, second Spool 320 underlying gas pressure is more than the elastic force of the second balancing spring 330, and the second spool 320 overcomes second The pressure of balancing spring 330 moves upward, and makes the second inlet end and the connection of the second outlet side.In the present embodiment, Force value B is 0.8MPa.
As it is shown on figure 3, as the pressure P of air accumulator, < during A, the first forced induction valve 200 is opened, the second pressure Power Inductance valve 300 is closed, and plunger shaft 140 is communicated in air vent 112, now no pressure in plunger shaft 140; It (is shown in Fig. 3 in the present embodiment that main valve plug 120 moves to one end under the effect of back-moving spring 130 Left end) initial position, groove 121 connects air pump interface 113 and air accumulator interface 111, and air pump is to storage Gas tank is inflated, now air pump band load work.
As A≤P, < during B, the first forced induction valve 200 and the second forced induction valve 300 are turned off, main valve Core 120 is still located at the initial position of one end (being the left end shown in Fig. 3 in the present embodiment), air pump interface 113 are communicated in air accumulator interface 111, and plunger shaft 140 disconnects with air vent 112, but now due to plunger shaft In 140, no pressure main valve plug is still located at initial position, and air pump continues to inflate to air accumulator, and now air pump band carries Work.
As shown in Figure 4, as P >=B, the first forced induction valve 200 is closed, the second forced induction valve 300 Open, after the gas of air accumulator is by pressure passage 114 and piston intake passage 115, enter plunger shaft 140, Drive main valve plug 120 overcome the pressure of back-moving spring 130 move to the other end (the present embodiment is in Fig. 3 Shown right-hand member), groove 121 connects air pump interface 113 and air vent 112, make air pump interface 113 with Air accumulator interface 111 disconnects, and allows air pump unloaded operation, enters power save mode.
When automobile open braking gas time, reservoir pressure P reduce, when low to P < during A, the first feeling of stress Answering valve 200 to be again turned on, the second forced induction valve 300 is again switched off, and plunger shaft 140 is communicated in air vent 112 pressure releases, main valve plug 120 resets under spring force to left movement, makes air pump break with air vent 112 Open, and be communicated in air accumulator, again inflate to air accumulator, now air pump band load work (as shown in Figure 3) again.
When A≤P < during B, plunger shaft 140 disconnects with air vent 112, air pump continue to air accumulator inflate, Air pump still band load work (as shown in Figure 3).
As P >=B, air pump unloaded operation again, enter power save mode (as shown in Figure 4).
So, air accumulator interface 111 is controlled by the first forced induction valve 200 and the second forced induction valve 300 With the break-make of plunger shaft 140, thus the position of control bound core 120, make air pump too small at reservoir pressure Time band load work, when reservoir pressure reaches certain value unload, enter power save mode, so circulate work, I.e. reach energy-conservation purpose.
These are only presently preferred embodiments of the present invention, not in order to limit the present invention, all the present invention's Any amendment, equivalent and the improvement etc. made within spirit and principle, should be included in the guarantor of the present invention Within the scope of protecting.
