Description

The four cycle engine reaper of the float type}

The subject of this invention is to install a float type carburetor in an engine with a displacement between 20 and 50 cc in a four-stroke engine.

In general, a conventional mower is a float type vaporizer for a two-stroke engine and a diaphragm-type vaporizer for a four-stroke engine as shown in FIG. 1. However, this conventional method has the following problems in practical use. First, the two-stroke engine in the engine type consumes more fuel than the four-stroke engine, and is more prone to smoke due to incomplete combustion, and carbons tend to be deposited in the spark plug or the exhaust and intake holes. In the carburetor type, as shown in FIG. 1, the diaphragm vaporizer uses a rubber diaphragm (1), so that the rubber material reacts directly with toluene and hardens, and the pin (2) and the screw at the bottom of the carburetor body are hardened. (3) has the disadvantage of easy to rust and frequent breakdowns.

The mower of the present invention compensates for the above drawbacks by installing a float type carburetor on an engine of 20 to 50cc displacement among four stroke engines, and has an advantage that the float type carburetor is much easier even when troubleshooting. In terms of structure, the float type carburetor has the advantage that the fuel tank is located higher than the carburetor, so that fuel flows naturally and there is less trouble in the carburetor part.

FIG. 2 is an assembly view of the float type vaporizer, and is composed of an upper body portion 101 and a lower float chamber 102 as shown in the figure, and between the body portion 101 and the float chamber 102. Gasket 135 is configured to prevent the leakage of fuel or oil, the upper portion of the body portion 101, the throttle valve 103, needle jet 104, creep 105, retire 106, spring ( 107), the cap body 108, the cap 109, the pipe 110 is composed of a nut 111, the end cable 112, the cap 113 at the end of the '-' pipe (110) It is composed of One side of the body is assembled with a gasket 114, a fuel coke combination 115, a filter 116, a gasket 117, a bolt 118, and the other side of the surface is a spring 119, a screw 120 , 'A' shaped pipe 121, the front part is assembled in the order of choke valve 122, washer 123, nut 124, lever (125), bolt (126), gasket ( 127 is assembled to the rear portion, and the lower portion of the body portion 101 in the order of the screw 128, jet needle 129, main jet 130, needle valve 131, float arm 133 The float arm 133 is assembled with the body portion 101 by a pin 132 that serves as a hinge on one side. In addition, there is a float 134 having a function of maintaining a constant oil level in the cylindrical float chamber 102 having an open upper side, thereby preventing oil leakage. The stay 136 is located below the float chamber 102. ) And a screw 137.

3 is a perspective view of a four-stroke engine mowing machine having a float-type vaporizer according to the present invention, a four-stroke engine engine body 201 having a displacement of 20 to 50 cc, and a fuel tank 202 above the engine body 201. And a vaporizer 203 and an air cleaner 204 formed on the side of the engine body 201, a fuel supply pipe 205 for supplying fuel from the fuel tank 202 to the engine body 201, and A clutch 206 formed on the other side of the engine body 201, a flexible cable 207 connected to the clutch 206 and freely movable, and one end of the flexible cable 207 are coupled by a connecting member. Working shaft 215, a loop handle 210 and a safety cover 211 formed on the working shaft 215, a gear case 213 and a cutter blade formed at one end of the working shaft 215 ( In addition, a throttle lever 209 is configured on one side of the working shaft 215. Adjust the rotational speed of the cutter blade 212. Reference numerals are tube clamp 216, grip 217, joint pipe 208, backrest 218, tank band 219, shoulder band 220 The fuel tank 202 is formed on the engine body 201 of the four-stroke engine, and the air cleaner 204 is formed on one side of the body, and the engine body 201 is provided. A float type vaporizer 203 is mounted between the air cleaners 204. The fuel is supplied to the vaporizer 203 along the fuel supply pipe 205 from the fuel tank 202 in a rectifying manner, and the fuel tank ( Since 202 is located above the vaporizer 203, fuel can be supplied more smoothly.

As described above, this mower can reduce oil consumption, engine noise, and exhaust gas by using four-stroke engines, and four-stroke engines use only gasoline as fuel, so there is no balance, and there is no carbon generation. It has the advantage of being longer. In addition, since the fuel flows more smoothly by using a float type carburetor, it is possible to expect less failure than a diaphragm type carburetor, and in particular, it has an advantage of easier repair in the event of a failure.
