Compression and exhaust event.The above-mentioned setting of outlet 112 is able to ensure that gas completely into in capacity chamber 42.
As shown in Fig. 9, Figure 27, in the pump assembly of embodiment one, the outlet 112 of air intake passage 11 is curved.Arc
The outlet 112 of structure can not only weaken air whirl phenomenon, moreover it is possible to reduce caused noise in intake process, and then improve and use
Family usage experience.The structure of said structure is simple, is easily worked.
As shown in Figure 9 and Figure 10, in the pump assembly of embodiment one, upper flange 10 is additionally provided with exhaust passage 12, row
Gas passage 12 connects with exhaust clearance 41.Specifically, after gas completes air-breathing and compression in pump assembly, and in steam vent 31
Gas pressure value be more than the pressure (pressure at expulsion) of exhaust clearance 41, exhaust valve plate 71 is opened, then gas is from capacity chamber
42 enter in exhaust clearance 41, are discharged to free surrounding space by exhaust passage 12 afterwards (in the housing of pump assembly).
Alternatively, horizontal plane of the discharge directions of exhaust passage 12 where with cylinder 30.It can so prevent from row
The housing outside gas blow-through pump assembly that gas passage 12 is discharged, reduces noise caused by exhaust process.
Specifically, air-breathing, compression, the exhaust process of pump assembly are illustrated by taking one of cavity as an example, it is as follows：When the chamber
When room connects with air intake passage 11, gas is entered in capacity chamber 42 by outlet 112, is started air-breathing and (be refer to Figure 28, figure

Second slip hole of piston coordinates and driving piston movement, then piston makees reciprocal fortune relative to rotating shaft in the first glide direction
Dynamic, while piston is relative to pivot, the first slip hole of piston and cylinder is slidably matched, then band of the cylinder in piston
Rotated under dynamic, then piston relative to cylinder in the second glide direction it is reciprocating.Due to the first glide direction and the
There is sliding angle between two glide directions, and piston carries out the superimposed motion of the first glide direction and the second glide direction, then
The connected state of exhaust clearance and capacity chamber can be changed during piston movement, so as to realize the air-breathing of pump assembly,
Compression and exhaust work, ensure pump assembly normal operation.
There is exhaust clearance between the cylinder and cylinder jacket of the application middle pump body component, will not occur directly to contact, then two
Be not in due to energy loss caused by rubbing action between person.So, the pump assembly in the application can reduce due to
Energy loss caused by being rubbed between cylinder and cylinder jacket, and then improve the capacity usage ratio of pump assembly.Meanwhile in the application
The pump assembly phenomenon that can prevent due to rubbing action and produce heat energy occur, and then improve the work effect of pump assembly
Rate.
