Description
Technical field
The present invention relates to air compressor, relate in particular to a kind of air compressor unloading device.
Background technique
Automobile-used air compressor is wanted off-load when air pressure reaches setting air pressure, the mode of off-load at present has two kinds, a kind of is the exhaust off-load, a kind of is the air inlet off-load, wherein the exhaust off-load is a kind of incomplete off-load, because it is its inlet and outlet valve block all will be worked, all unfavorable to life-span, the reliability of air compressor like this; And the air inlet off-load especially adopts the air compressor of Reed Valve intake and exhaust structure to seem comparatively difficult, domestic and international existing technology is at present, set up an off-load valve block, put a piston structure on the cylinder cap, the off-load valve block blocks unloading hole when inflating, during off-load, enter the plunger head chamber, promote plunger the off-load valve block is moved up to leaving unloading hole from the pressurized air of pressure regulator valve.It is floating type that second kind of form is that air-intake valve plate is made, and it can be along the axis translation, and till leaving inlet hole, its driving gas is realized by the plunger that is located at cylinder sleeve top.The third form is that plunger is differential, its working principle is that two O type circles are arranged on the plunger, covered an O type circle, after two cooperations on plunger the hole form a Seal cage, an aperture is arranged at this bottom, chamber, communicate with the cylinder sleeve top by the unloading hole on the seat board, and plunger leans on the spring force pressure on top on plane on the seat board, form sealing, the gas force on cylinder sleeve top loculus eternal and plunger upper part balances each other, and unloading hole is less than the area of plunger bottom, gas force can not make the lift off a seat unloading hole plane of plate of plunger lower plane (sealing surface) like this, and during off-load, pressurized air from pressure regulator valve enters into the big footpath of plunger and the chamber between the path, because the relation of pressure reduction makes the up plate of lifting off a seat of plunger reach the purpose of off-load, there are two problems in this structure, the one, it is bigger that unloading hole can not be done, the volume that this can influence plunger causes overall structure to strengthen, and the 2nd, its cushion rubber is more, fitting surface is many, tighter to the behaviour in service requirement like this, so reliability is relatively poor, the 4th kind is the little valve block formula in straight top, also exist cushion rubber more, fitting surface is many, like this behaviour in service is required tighter, so shortcoming such as reliability is relatively poor.
Summary of the invention
In order to solve the problem of above-mentioned existence, the invention provides a kind of simple in structure, air compressor unloading device that off-load is effective.
Technological scheme of the present invention is to realize like this, a kind of air compressor unloading device, comprise seat board, off-load sheet, offer an annular groove, through hole is set in annular groove at the lower plane of seat board, the side of annular groove is opened an elongated slot and is communicated with annular groove, the off-load sheet is arranged in the annular groove, has the unloading hole identical with through hole on the seat board on the off-load sheet, and a tooth bar is installed in the seat board elongated slot, tooth bar is provided with a pin-and-hole, and tooth bar links to each other with the off-load sheet.
Off-load sheet wherein is the off-load sheet of band portion profile of tooth.
Unloading hole on the off-load sheet big or small identical.
Compared with prior art the invention has the beneficial effects as follows: the present invention is simple in structure, and off-load efficient height has been cancelled more cushion rubber of the prior art, and it is not very strict therefore behaviour in service being required.

Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail, but not as a limitation of the invention.
As shown in Figure 3, offer unloading hole 2 on the off-load sheet 12, off-load sheet 12 part sides have profile of tooth, and off-load sheet 12 has the side and tooth bar 5 engagements of profile of tooth, the mobile rotation that will drive off-load sheet 12 of tooth bar 5 like this, and tooth bar 5 is provided with tooth bar pin-and-hole 6.
As shown in Figure 1, off-load sheet 12 among Fig. 2 and tooth bar 5 are installed in the respective grooves of offering on the seat board 11 among Fig. 3.A kind of air compressor unloading device, comprise seat board 11 and off-load sheet 12, offer an annular groove 1 at the lower plane of seat board 11, through hole 3 is set in annular groove 1, through hole 3 communicates with air-inlet cavity on the cylinder cap 10, the side of annular groove 1 is opened an elongated slot 4 and is communicated with annular groove 1, off-load sheet 12 is for having the off-load sheet 12 of part profile of tooth, it is arranged in the annular groove 1, have several and the identical unloading hole 2 of through hole 3 on the seat board 11 on the off-load sheet 12, one tooth bar 5 is installed in the elongated slot 4 of seat board 11, and tooth bar 5 is provided with a tooth bar pin-and-hole 6, and tooth bar 5 links to each other with off-load sheet 12.
As shown in Figure 4, the through hole 3 identical with unloading hole 2 that is provided with in the annular groove 1 of seat board 11 communicates with cylinder cap 10 air-inlet cavitys, link to each other by the plunger pin-and-hole 9 that is provided with on the tooth bar pin-and-hole 6 on the tooth bar 5 and the plunger 7 that is located at cylinder sleeve 13 upper side, pass through moving of plunger 7 like this, drive moving axially of tooth bar 5, drive the rotation of off-load sheet 12 by tooth bar 5, thereby make in the process of inflating on the off-load sheet 12 unloading hole 2 and annular groove 1 in through hole 3 alternate and the state that seals, the mobile sealing state that makes by tooth bar 5 is destroyed, and become the all-pass state, and realize off-load.The theoretical displacement that how much depends on air compressor fully of unloading hole 2, and the locating face up and down of off-load sheet 12 and tooth bar 5 is groove planes of seat board 11, opposite side then is the metallic shim 8 between seat board 11 and cylinder sleeve 13, and it promptly has the effect of pad to play the location again.
