Description

Rotary-piston machine

Affiliated technical field: the present invention is a kind of rotary-piston machine that can be applicable to motor and fluid pump, should will be referred to dependent part groups such as International Classification of Patents F01C1/344 and F04C2/344.

Background technique: motor and pump be working principle to basic structure can be extremely similar and two class different products that function is obviously distinguished.As the motor or the pump of variable capacity, corresponding all have reciprocating piston type, rotation or pendulum piston type and other form.By the relevant note in the International Patent Classification (IPC): the motor of rotary-piston type, pump or machinery are meant that fluid Contact Transmission element rotate or around along circular or be similar to variable capacity motor, pump or the machinery that axle that circular trace moves rotates around stationary axle therein.They also all have corresponding prior art separately.Because the work cycle process of rotary engine: the suction process of the variable capacity of air-breathing-more corresponding form pump of variable capacity compression-variable capacity expansion-exhaust wants complicated relatively, must also have the process of fuel gas buring expansion working.Thereby in general, being commonly called as the corresponding simplification of the rotary engine of rotary engine, the fluid pump that just can make corresponding form uses; But then not necessarily has reversibility conversely.Therefore with regard to background technique, as long as the invention that existing relatively rotary engine has patentability, the fluid pump that is formed by the corresponding simplification of its basic structure also must have patentability.That the inventor has, on May 14th, 2003 notice of authorization, the patent No. is the ZL00126651.9 patent, is exactly a kind of and the closely-related background technique of the present invention.It is the inboard wall of cylinder block face intersects two circular curve profiles of circular arc formation for size two a rotary engine.Show through corresponding model machine running in and further analysis and research: in this machine working procedure, satisfying the requirement of the airtight property of motor, setting up on the desired working pressure with assurance, also there are two relative deficiencies in its basic structure.One, the cylinder inner wall profile of two circular arcs formations, in its working procedure, rotor and blade are rotating center with this two crossing center of arc respectively, do rotatablely moving of decentraction.In the rotation, the vane rotor intercropping adapts to the required relative movement of running, and the blade end face moves on the circumferential surface that orthodrome constituted from start to finish.When blade is in the orthodrome section, the end face of blade contacts with the orthodrome cylinder of casing wall all the time, thereby can guarantee the corresponding tightness requirement in working room that adjacent two blade and casing walls are surrounded.Be in roundlet arc section as blade, the relative roundlet arc column of its end face cylinder wall surface contracts in being and is discontiguous.The tightness of working room is only by the applying of rotor and inboard wall of cylinder block face and realize poor effect.Thereby two circular arc molded lines cylinder wall surface are difficult to guarantee corresponding tightness requirement in the whole work cycle.Two, for satisfying that rotor drives that installing blade is wherein done with revolution but the requirement that rotatablely moves of decentraction, adopt blade with its blade setting-in to the rotor in the corresponding trapezoidal conduit, be installed on the installation axle bed that corresponding and rotor center are setovered on cylinder body or the cylinder cap from the distolateral fitting seat hole of stretching out of blade again.Though this structure is done decentraction when rotation at rotor blade, can adapt to turn round in required relative movement between vane rotor, the relative complex of structure own, more elasticity air seal piece 9 need be set and guarantee corresponding sealing.Its sealing configuration is because sealing surface is less with the sealing force that applies, and sealing effect is not good yet, thereby the tightness of rotary engine is greatly affected again.

Goal of the invention: provide a kind of and can satisfy the former No. 00126651.9 patent of invention task of the inventor, but on the structure corresponding simplification still can satisfy relative movement that vane rotor does decentraction when rotation around fixed center respectively require, eliminated again above-mentioned defective, and can be for the rotary-piston machine of rotary engine or fluid pump use.

The technological scheme of innovation and creation: rotary-piston machine contains cylinder body 1, rotor 2, and blade 3, cylinder side cover 4, the appropriate position is respectively equipped with

device

5,6 and the main shaft 7 that enters, discharges inner chamber of cylinder block for working fluid on the cylinder body; Rotor 2 is loaded on the main shaft 7, constitutes the synthetic stator of the cylinder body 1 of inner wall surface thereof and side cover 4 by the circular arc molded lines, with rotor and uniformly be installed in the rotor conduit, N blade encirclement with respective diameters circular arc end face wherein; The rotating center biasing that rotor, blade are fixing respectively; The rotor banding moving vane is done with revolution but the rotatablely moving of decentraction, and has the corresponding connecting structure that can satisfy desired relative movement between them and guarantee required sealing between the vane rotor stator; It is characterized in that: the inboard wall of cylinder block profile is the cylndrical surface of, diameter concentric with the blade rotating center and blade arc end face equal diameters.

Beneficial effect: the present invention is applied to rotary engine, and the end face of its blade still keeps being fitted on the inboard wall of cylinder block circumferential surface makes circular movement, and blade movement is not steadily, can bite to casing wall.The beneficial effect that had both kept former No. 00126651.9 patent has overcome its drawback again.Be improved to single cylndrical surface because inside wall of cylinder profile intersects the circular arc cylinder by two, simple in structure, good manufacturability is the excellent characteristics of maximum of the present invention.As motor, its compression ratio height; Then discharge capacity is big as pump.The round line of list of the present invention is in addition compared with the outer spinning roller molded lines of two arc circles that intersects two circular arc molded lines or triangular-piston rotor machine that two radius does not wait, not only structure is greatly simplified, and do not resemble they corresponding should arrange two blades or three scraping blades, as long as the corresponding meticulous rational deployment of energy in the inlet and exhaust valve design, 2 blades not only can be set, also be not difficult to be provided with the variation requirement that 3 and even 4 blades can both better satisfy air-breathing in the engine operational cycle-compression-expansion-exhaust process, should rise progressively gradually or fall progressively volume of cylinder.Then the restriction meeting to the blade number was littler when it was used in fluid pump.
