Description
One, technical field
The present invention relates to a kind of many circular arcs cylinder body Slidine-vane rotor displacement machine, belong to motor, gas compressor and liquid delivery pump class displacement machine technical field.
Two, background technique
1, at present patent applied for or the motor class displacement machine invention that patents mainly contain reciprocating-piston engine, wankel triangle rotary engine etc.Wherein reciprocating-piston engine expands at the space combustion of cylinder block and cylindrical piston encirclement by mixing combustion vapour, promotes piston along the cylinder body axial-movement, produces power, its major advantage is a cylinder body, piston-shaped simple, easy to process, adopt piston ring packing, leak less; Shortcoming is that piston is done straight reciprocating motion, and piston power needs to spread out of by connecting rod, and parts are many in addition in to-and-fro motion, and inertial force is big, causes vibration big, and rotating speed can not be too high and output torque is lower.Wankel triangle rotary engine piston-shaped near triangle, the inner chamber of cylinder block shape is near 8 fonts, piston is controlled jointly by eccentric internal gear pair and eccentric shaft, three summits of assurance piston contact with cylinder body in eccentric rotary course all the time, form three cavitys that volume constantly changes, and finish air-breathing, compress, burn, expand acting, exhaust process, its advantage is a crankshaft-free connection rod, piston does not move reciprocatingly, so there is not reciprocal inertia force, vibrates less; Shortcoming is that cylinder body shape line and piston shape line processing request are accurate, and the shape line is special, the difficulty of processing height, in addition because there are periodic eccentric force in eccentric shaft and eccentric internal gear pair, still have vibrations to a certain degree, the pto of eccentric shaft directly is subjected to Influence from Eccentric simultaneously, and size and intensity are restricted.How to find a kind of crank piston that do not have, pto intensity height, piston-shaped simple, new work engine easy to process is the problem of being concerned about in the industry.By applicant's retrieval and inquisition, do not find that as yet prior art or patent adopt cylinder body shape line that present patent application proposes or similar and this cylinder body to cooperate the motor combination that forms with sliding blade.
2, patent applied for or the compressor that patents and pump class displacement machine invention at present mainly contains reciprocating piston gas compressor, eccentric vane rotor pump etc.Wherein reciprocating-piston compressor is passed to cylindrical piston by connecting rod with power, piston in cylinder block along the cylinder body axial-movement, cooperate with the inlet and outlet valve, finish compression process, its major advantage is a cylinder body, piston-shaped simple, easy to process, adopt piston ring packing, leak less; Shortcoming is that piston is done straight reciprocating motion, and piston power is transmitted by connecting rod, and parts are many in addition in to-and-fro motion, and inertial force is big, causes vibration big, and rotating speed can not be too high.Eccentric vane rotor pump adopts single circular cylinder body and the configuration of circular eccentric rotor, blade is subjected to spring force or centrifugal action and slides in cylinder body or the groove on eccentric rotor, when pump rotates, because the variation of position between eccentric rotor and cylinder body cooperates the flexible of blade, forms suction, discharge process, its advantage is not have reciprocal inertia force substantially, vibration is much smaller than piston compressor, and shortcoming is because there is eccentric force in eccentric rotor when rotating, and still can cause the vibration of certain intensity.What the present invention was different with pump with above gas compressor is that cylinder shaped conductor is made up of the circular arc of a plurality of different circles, the piston shaft that adopts geometrical axis to overlap with rotation axis, slide in the groove of sliding blade on piston shaft, inner chamber is surrounded by cylinder body, piston shaft, blade and the end cap at axial two ends and forms, clockwise or the counterclockwise direction rotation along with piston shaft, form suction, compression and discharge process, piston shaft whenever turns around, finish overall process simultaneously 2 times, owing to do not have crank-connecting rod and eccentric rotor, vibration is lighter.By applicant's retrieval and inquisition, do not find that as yet prior art or patent adopt that present patent application proposes or similarly cylinder shaped conductor and this cylinder body cooperate formation compressor or pump to make up with sliding blade.
Three, summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art, provide a kind of and have than light with the vibration of power conventional engine, that moving element lacks, output torque is high many circular arcs cylinder body Slidine-vane rotor positive-displacement engine and than light with the vibration of discharge capacity reciprocating piston type gas compressor, that moving element lacks many circular arcs cylinder body Slidine-vane rotor positive-displacement compressor or pump.
Technological scheme of the present invention is that it comprises cylinder body, piston assembly; It is characterized in that the molded lines of cylinder body is made up of a plurality of circular arcs; The sliding blade mutual group that is equipped with in piston shaft and its groove becomes piston assembly; Surround by piston shaft, cylinder body, sliding blade with at the axial end cap at two ends and to form the motor inner chamber; Circular arc line by cylinder body and the sliding blade on the piston shaft cooperate and form a plurality of closed inner chambers of continually varying, finish suction, the discharge process of suction, compression, discharge process or pump of air-breathing, compression, burning, expansion, exhaust process or the gas compressor of motor.
Piston shaft of the present invention does not move reciprocatingly, and does not have reciprocal inertia force and eccentric force during rotation; The centrifugal force of blade is very little, and can partly cancel out each other; Do not need the inlet and outlet valve.Compare with the Reciprocating engine of existing same displacement with many circular arcs cylinder body Slidine-vane rotor positive-displacement engine of the invention process, volume can dwindle over half; Compare with the reciprocating-piston compressor of existing same displacement with many circular arcs cylinder body Slidine-vane rotor positive displacement compressor of the invention process, volume can dwindle more than 1/4th.
