Abstract

The utility model provides an H type concave three lobe rotor piston engine, comprising a cylinder and a three lobe rotor. The side face of the three lobe rotor is in an H shape, and the inwards concave cambered surface of a planetoid track is arranged between two contiguous angles. The front-half section of the cambered surface is provided with a concave path, and the inwards convex position of the cylinder is provided with elastic sealing slices. The front end of one sealing slice is provided with a combustion chamber, and the back end is provided with a unidirectional exhaust valve which is communicated with an oil inlet pipeline. The front end of the other sealing slice is provided with an air suction port, and the back end is provided with an exhaust port. The utility model is provided with a sealing slice between the exhaust port and the air suction port for preventing the oil gas from exhausting along with the exhaust gas. When the combustion chamber is ignited, the back-half part of the inwards concave cambered surface of the rotor pushes against the unidirectional exhaust valve to release the pressure proceeding with negative work and discharge the oil gas back to the oil inlet system. Under the condition that the air displacement and the compression ratio are same, the oil consumption is decreased by 46%, the end gas discharge capacity is decreased by 51%, the maximum torque and the power are improved by 2. 6 times, the weight and the volume are decreased by 2/3, the cost is decreased by 1/4, and the service life is improved by three times.

Description

The recessed three-apexed rotor piston engine of a kind of H type

Technical field

The utility model is a kind of motor, the recessed three-apexed rotor piston engine of particularly a kind of H type.

Background technique

Put on display the RX8 sport car that is called as unique in the world protruding rotary polygonal piston engine configuration in the Tokyo car exhibition in November calendar year 2001.All can there be being communicated with of moment between the output power height of this motor, but because in each operation cycle of rotor, intakeport and relief opening, the oily vapour that enters is discharged with waste gas, cause the increase of fuel consumption and the pollution of air; Perhaps make the waste gas that discharge enter intakeport, reduce the ratio of oily vapour, influence the efficient of motor.Next be since between epitrochanterian diaphragm seal and the cylinder inner wall for line contact, resemble three sharp knives and on cylinder inner wall, scrape, on cylinder inner wall, occur wavy chatter mark soon and wear and tear, lacked the working life of cylinder.

Summary of the invention

The purpose of this utility model provides a kind of novel engine, and it can overcome existing shortcoming in the prior art, reduces oil consumption rate, and next improves working life.

The purpose of this utility model is achieved in that it comprises cylinder and three-apexed rotor, cylinder inner cavity has two place's convexes, the end, angle of three-apexed rotor is provided with elastic sealing strip, it is characterized in that the three-apexed rotor side is the H type, be the inner concave shape cambered surface of orbital path between its adjacent two jiaos, cambered surface goes forward half section to have recessed road, cylinder convex place is provided with elastic sealing strip, the front end of one of them diaphragm seal is that firing chamber, rear end are equipped with one-way exhaust valve Men Bingyu in-line and are communicated, and the front end of another diaphragm seal is that intakeport, rear end are relief opening.

Said structure of the present utility model has following advantage: owing between relief opening and intakeport diaphragm seal is installed, prevented that oily vapour from discharging with waste gas; Epitrochanterian inner concave shape cambered surface makes the arm of force lengthening of rotor; When the moment of firing chamber igniting, rotor inner concave arc surface latter half of under pushed at high pressure backs down the one-way exhaust valve door, the pressure that this part is done negative work discharge and with oily vapour discharging back into oil system.So under the identical situation of air displacement, compression ratio and spindle speed, fuel consumption of the present utility model descends 46%, the tail gas blowdown flow rate descends 51%, Max. torque and power improve 2.6 times, weight and volume has reduced by 2/3, and cost reduces by 1/4, and be original twice working life.

Embodiment

The utility model is described in more detail below in conjunction with embodiment and accompanying drawing thereof.

1 is bent axle among Fig. 2, and bearing 9 is installed on bent axle, and external gear 2 and rotor 7 are housed, and internal gear 3 is fixedly connected with rotor and be meshed with external gear 2, the 8th, and flywheel, the 4th, cylinder.As seen from the figure, the side of rotor is the H type, and intermediate portion is the working surface of rotor, and Stamping Steel Ribbon 12 as shown in Figure 3 and Figure 4 and wave mode spring 13 are installed in the two ends of cylinder bearing face.

As seen from Figure 1, the cross section of the active section of H type rotor 7 is the indent triangle, it is the inner concave arc surface of forming for orbital path between leg-of-mutton two adjacent angular, on preceding half section of cambered surface, have simultaneously recessed road 5 as shown in Figure 5, the wave mode spring 12 of diaphragm seal 11 and realization diaphragm seal elastic telescopic is installed on three summits of rotor 7.For reducing the scratch to cylinder inner wall, the surface of contact of diaphragm seal is designed to cambered surface, and contacts for cambered surface between the cylinder.The inwall of cylinder 4 has the convex of two symmetric arrangement, is provided with sealing in the prominence, and diaphragm seal 11 and spring 12 are installed, the front end of Shang Mian projection K place diaphragm seal is the firing chamber in the drawings, spark plug 14 is installed, and the rear end has through hole, and one-way exhaust valve door 6 is installed.Following projection Q place front end is an intakeport, and the rear end is a relief opening.

Claims
