Abstract
An eccentric shaft 1 is arranged at the central part of a cylinder body 7 of the utility model, an eccentric rotor 2 is sheathed out of the eccentric shaft, and a cylindrical piston 3 of which the lumbar part forms a concave shape is sheathed out of the eccentric rotor 2. The utility model has the characteristics of simple and compact structure, convenient manufacture and maintenance, small size, light weight, low cost, etc. The utility model can be widely used in hydraulic pumps, hydraulic motors, and piston type compressors.
Description
The utility model relates to a kind of mechanical type piston apparatus, especially shows to adopt the eccentric dynamic piston apparatus.
At oil hydraulic pump and piston compressors such as existing gear pump, reciprocating pumps, it is big all to exist the big noise of impact shock, and volume is big, body weight, cost height, deficiencys such as inconvenient maintenance." a kind of miniature fluid-feed pump device " still exists above-mentioned deficiency in number of patent application 91213974.9 patent disclosures.
The purpose of this utility model provides a kind of simple and compact for structure, makes easily, and impact shock is little, and noise is low, and a kind of eccentric dynamic piston apparatus can effectively be provided.
The purpose of this utility model is to realize like this, include upper and lower covers, outlet valve assembly, inlet valve assembly, cylinder body, its cylinder body middle part is mounted with eccentric shaft, and eccentric shaft is with eccentric rotor outward, and eccentric rotor is with the piston that columniform waist is spill outward.
The piston crown of piston of the present utility model is provided with inlet passage.
The utility model is by means of a secondary eccentric shaft, eccentric rotor comes transferring power, to rotatablely move and become linear reciprocating motion, eccentric shaft rotates a circle, piston is finished a reciprocation cycle motion, device is finished twice suction, the process of row's medium, promptly by prime mover (motor, motor) drive the eccentric shaft rotation, eccentric rotor is along with eccentric shaft rotates, and its resultant motion is a straight line motion, the promotion piston does reciprocating linear motion, thereby the volume at cylinder body two ends is changed, and medium (liquid or gas) enters in the cylinder body by import, discharges cylinder body by outlet under the promotion of piston, make medium obtain pressure and speed, thereby finish the task of fed sheet of a media.
Because adopt technique scheme, the utility model is compared with prior art, and is simple and compact for structure, make easy to maintenance, characteristics such as volume is little, and is in light weight, and cost is low.Can be widely used in oil hydraulic pump, oil hydraulic motor and piston compressor.
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is the utility model sectional structure schematic representation.
Among the figure: 1-eccentric shaft 2-eccentric rotor 3-piston 4-upper and lower covers 5-outlet valve assembly 6-inlet valve assembly 7-cylinder body 8-inlet passage
As shown in drawings, upper and lower covers 4 and cylinder body 7 are formed inner chamber, and the cylinder body middle part is mounted with eccentric shaft 1, the eccentric shaft 1 outer eccentric rotor 2 that is with, the eccentric rotor 2 outer pistons 3 that are with, piston 3 heads have inlet passage 8 and inlet valve assembly 6 are housed, and upper and lower covers 4 is equipped with outlet valve assembly 5.
Claims (2)
1. eccentric dynamic piston apparatus, include upper and lower covers (4), outlet valve assembly (5), inlet valve assembly (6), cylinder body (7), it is characterized in that cylinder body (7) middle part is mounted with eccentric shaft (1), the outer eccentric rotor (2) that is with of eccentric shaft (1) is with the piston (3) that columniform waist is spill outside the eccentric rotor (2).
2. a kind of eccentric dynamic piston apparatus according to claim 1 is characterized in that the head of piston (3) is provided with inlet passage (8).
