Specific embodiment
Technical scheme described in the present patent application is described without limitation below in conjunction with accompanying drawing, it is therefore an objective to be
The public more fully understands the technology contents.
As shown in Figure 1-2, it is a schematic diagram of one embodiment of single pump of pump described in the present patent application, should
Independent pump, including the pump housing 1 with pump chamber 2, be provided with pump chamber 2 can be reciprocating pull bar 3,
Pull bar 3 can be in the driving of drive device (such as including but is not limited to cylinder, motor and transmission mechanism etc.)
Under move back and forth, the pump housing 1 is provided with two tube chambers communicated with pump chamber 2, respectively the first tube chamber 51
With the second tube chamber 52, one end of each tube chamber communicates with pump chamber 2, and the other end leads to outside the pump housing 1, each pipe
The accommodating chamber for placing valve element (respectively the first valve element 41 and the second valve element 42), respectively first are provided with chamber
The accommodating chamber 62 of accommodating chamber 61 and second, valve element can be moved and do not fallen out in each residing accommodating chamber, the
The one end of one accommodating chamber 61 is connected with the first tube chamber 51 by the first access port 81 and leads to pump chamber 2, and the other end leads to
Cross first outlet 71 and be connected with the first tube chamber 51 and lead to outside the pump housing 1；The one end of second accommodating chamber 62 passes through second
Access port 82 is connected with the second tube chamber 52 and leads to pump chamber 2, and the other end passes through the tube chamber of second outlet 72 and second
52 are connected leads to outside the pump housing 1；First valve element 41 can completely enclose the first access of residing first accommodating chamber 61
Mouth 81, and the first outlet 71 of residing first accommodating chamber 61 can not be completely enclosed, and the second valve element 42 can be complete
The second outlet 72 of totally-enclosed residing second accommodating chamber 62, and residing second accommodating chamber 62 can not be completely enclosed
The second access port 82.I.e. different valve elements are only capable of one end of accommodating chamber where closing, and can not close different appearances
Receive the same direction in chamber.
The operation principle of single pump, with reference to accompanying drawing 1-2, is described in detail as follows：In this embodiment, with
Two tube chambers 52 are low pressure liquid feeding end, and the first tube chamber 51 is high pressure outlet end, and 3 is pull bar (piston rod),
Wherein, first outlet 71 is incomplete blind end, and second outlet 72 is completely enclosed end, the first access port
81 is completely enclosed end, and the second access port 82 is incomplete blind end.When pull bar 3 is aspirated downwards, the
The second valve element 42 in two accommodating chambers 62 moves to incomplete blind end --- the second access port 82, low pressure liquid
Body is by incomplete blind end --- and second outlet 72 enters pump chamber 2；And the first valve element 41 moves to the first receiving
The completely enclosed end in chamber 61 --- the first access port 81, liquid past will not be flowed outwardly by the first tube chamber 51.
When pull bar 3 is boosted, the second valve element 42 moves to completely enclosed end --- second outlet 72, high pressure
Liquid will not the second tube chamber 52 flow outwardly；And the first valve element 41 moves to incomplete blind end --- first
Outlet 71, highly pressurised liquid is flowed out by the incomplete blind end of the first tube chamber 51；Thus by the reciprocal of pull bar
Motion, realizes that liquid is pressurized.
Embodiment one
Such as Fig. 3, the present embodiment is that an outer wall is shared between double pump, and the pump housing, each according to mentioned above
Individual single pump is capable of achieving the constant function of going out liquid from another tube chamber by a tube chamber feed liquor, in the present embodiment
In, two pumps are synchronous, including first pump housing 11 and second pump housing 12, and correspondence has the He of the first pump chamber 21
Second pump chamber 22, and the first pull bar 31 and the second pull bar 32, due to two pull bars 31 and 32
Synchronously do straight reciprocating motion so that the liquid turnover of first pump housing 11 and second pump housing 12 is synchronous, so
When two pull bars are pushed up simultaneously, liquid is respectively by first pump housing 11 and second pump housing 12 while pump
Go out, realize pressure output higher.
Embodiment two
Such as Fig. 4, the present embodiment is that an outer wall is shared between double pump, and the pump housing, each according to mentioned above
Individual single pump is capable of achieving the constant function of going out liquid from another tube chamber by a tube chamber feed liquor, in the present embodiment
In, two pumps are asynchronous, including first pump housing 11 and second pump housing 12, and correspondence has the He of the first pump chamber 21
Second pump chamber 22, and the first pull bar 31 and the second pull bar 32, due to two pull bars 31 and 32
It is asynchronous to do straight reciprocating motion so that the liquid turnover of first pump housing 11 and second pump housing 12 is in opposite direction,
So when two pull bars are alternately moved up and down, liquid all the time by first pump housing 11 or second pump housing 12 its
One of pump out, realize stabilization pressure output.
Obviously, in the pump described in the present patent application, single pump can respective independent separate, it is also possible to shared same
The shape of one outer wall, valve element and residing accommodating chamber can have various possible situations, and tube chamber cross section
Shape can also have various, and only need to meet valve element only closes accommodating chamber one end.
It should be understood that the above includes that accompanying drawing is not the limitation to the technical scheme, in fact,
Under identical or approximate principle, the improvement carried out to the technical scheme, including Each part shape,
Size, material used, and essentially identical functional structure equivalent, all required by the present patent application
Within the technical scheme of protection.
