Background technique

Present each industrial enterprise unit or the employed compressor pump of family (for example freezer, refrigerator, air conditioner, aeration pump), mostly adopt the reciprocating type compressor pump of piston reciprocating operation, or the rotary compression pump that adopts eccentric rotor to move, although that they all are current performances is more superior, use more general compressor pump, they have the one side of its deficiency, are exactly that volume is bigger than normal, complex structure, friction factor is high, and compressing force is powerful not, and electrisity consumption is large.

Summary of the invention

The objective of the invention is to provide a kind of small volume, and simple in structure, friction factor is little, and compressing force is more powerful, the rotary type compressor pump of rocker arm that is widely used in various high pressure pump systems that power consumption is less.

the present invention realizes in the following way, at one, be equipped with rocker box (1), rocker box (1) is built-in with rocking arm (2), be enclosed in to the movable property of its tail end and shake in interior rocking arm base (3) copper sheathing of wall case (1) or bearing (4), the middle lower end of its rocking arm should the property moved enter in below circular cylinder body (5) by rocker box hermetically, cylinder body (5) is built-in with an eccentric rotor body (6), eccentric rotor body (6) is comprised of the external core of eccentric rotor (7) and eccentric rotor body inner core (8), in the inner edge of the external core of eccentric rotor, should more closely insert bearing or copper sheathing (9), and in eccentric rotor body inner core (8) can flexible rotating ground can be packed into its bearing or copper sheathing (9), on the eccentric rotor body (6) of the external core of eccentric rotor (7), have a rocker shaft hole (10) that can be inserted in rocking arm (2) lower end, and can flexible rotating by rocking arm (2) lower end but will pack into more hermetically wherein, the external core of eccentric rotor (7) is packed on a side cylinder body of rocking arm lower end and is had air inlet (11), on the opposite side cylinder body, have exhaust outlet (12), eccentric rotor body inner core (8) is equipped with an eccentric shaft away from its central point (13), on all the other eccentric rotor body inner cores of eccentric rotor body inner core eccentric shaft (13), have depolarized hole (14), to reduce the vibration that is in operation and brings because of bias, eccentric shaft (13) on eccentric rotor body inner core should be enclosed in the central shaft hole (15) at center in cylinder body, any point on the external core of eccentric rotor (7) outer rim is in operation and all has an opportunity to be close to inboard wall of cylinder block, the external core outer rim of the eccentric rotor of remainder is away from the cylinder block inwall, Fig. 1.

The remarkable advantage of the present invention is that its purposes is wider, not only can make the refrigerant compression pump, but also can be used for the high flow capacity gas compression.

Another advantage of the present invention is that it is simple in structure, and friction factor is little, and volume is little, and is easy to manufacture, is convenient to popularize.

Embodiment

referring now to an accompanying drawing explanation specific embodiment of the present invention, at one, be equipped with rocker box (1), rocker box (1) is built-in with rocking arm (2), be enclosed in to the movable property of its tail end and shake in interior rocking arm base (3) copper sheathing of wall case (1) or bearing (4), the middle lower end of its rocking arm should the property moved enter in below circular cylinder body (5) by rocker box hermetically, cylinder body (5) is built-in with an eccentric rotor body (6), eccentric rotor body (6) is comprised of the external core of eccentric rotor (7) and eccentric rotor body inner core (8), the inner edge of the external core of eccentric rotor should more closely be inserted bearing or copper sheathing (9), and can be enclosed in eccentric rotor body inner core (8) in its bearing or copper sheathing (9) flexible rotating, on the eccentric rotor body (6) of the external core of eccentric rotor (7), have a rocker shaft hole (10) that can be inserted in rocking arm (2) lower end, and can flexible rotating by rocking arm (2) lower end but will pack into more hermetically wherein, the external core of eccentric rotor (7) outer rim is packed on a side cylinder body (5) of rocking arm lower end and is had air inlet (11), on the opposite side cylinder body, have exhaust outlet (12), eccentric rotor body inner core (8) is equipped with an eccentric shaft away from its central point (13), on all the other eccentric rotor body inner cores of eccentric rotor body inner core eccentric shaft (11), have depolarized hole (14), to reduce the vibration that is in operation and brings because of bias, eccentric shaft (13) on eccentric rotor body inner core should be enclosed in the central shaft hole (15) at cylinder body center, any point on the external core of eccentric rotor (7) outer rim is in operation and all can has an opportunity to be close to the cylinder block inwall, the external core outer rim of the eccentric rotor of remainder is away from the cylinder block inwall, as Fig. 1, formed a most preferred embodiment of the present invention.

space in cylinder block is divided into two parts by rocking arm, one side part of rocking arm communicates with air inlet, as low-pressure cavity, the opposite side part of rocking arm communicates with exhaust outlet, as high pressure chest, the gas that is come by air inlet or liquid enter the external edge of eccentric rotor in cylinder body and the space of rocking arm, when eccentric rotor body inner core rotates, band dynamic bearing or copper sheathing rotate simultaneously, thereby also driving the external core of eccentric rotor rotates, can make rocking arm than the operation up and down in cylinder and in rocker box of sealing ground, also making simultaneously the external core outer rim of eccentric rotor can have all the time any to be close to the moving property sealing of inboard wall of cylinder block ground rotates, the area of low-pressure cavity is increasing, gas or the liquid of inspiration constantly increase, and high pressure chest compressed diminishing gradually, finally by exhaust outlet Exhaust Gas or liquid, and the area of low-pressure cavity constantly enlarges, constantly suck again new gas or liquid, and the external core outer rim of eccentric rotor is pushed gas or liquid through air inlet by after exhaust outlet to the exhaust outlet direction, compression, the exhaust outlet of discharging, so through circulation.
