20140084493 | SIMPLE STARTUP CARBURETOR - A carburetor improves the starting performance of an engine. The carburetor includes a main body, a pump oil ball and a fuel-air mixing channel which extends through the main body. The pump oil ball is mounted to an air strangler spindle via a spiral groove. When the pump oil ball is pressed, the air strangler spindle is driven to rotate by the spiral groove and thus to control the air strangler spindle between the fully open state and the fully closed state. The carburetor dramatically improves the starting performance of the engine. | 03-27-2014 |
20140196688 | ONE-STEP STARTING CARBURETOR - A one-step starting carburetor includes a body, and a pulse generator and an oil pumping unit which are connected with the body. The oil pumping unit can produce an oil pumping function to pump fuel from an oiler to the carburetor when a flywheel of an engine is revolving. When the carburetor is operating, it only needs to pull a starting line and does not need to extrude an oil pumping ball to pump the fuel for the carburetor or to close a choke valve. After hearing a voice like ‘poop-poop’, it does not need to half open the choke valve to warm the engine or to open the choke valve after warming the engine. Thus the operation of the carburetor is simple for users' convenience. | 07-17-2014 |
20140196689 | PULSE GENERATOR USED FOR A ONE-STEP STARTING CARBURETOR - A pulse generator used for a one-step starting carburetor includes a pulse chamber, a lower cover, a support and a solenoid valve. Two types of pulse are produced in the pulse chamber: the normal pulse and the crowding pulse. The normal pulse provides the normal pulse force for the carburetor. When the engine starts in cold, the crowding pulse goes into the carburetor to concentrate the gas mixture in a mixing chamber of the carburetor. The pulse generator described herein solves the problem that the pulse force is insufficient in the four-stroke engine. The original suction pulse is modified to two directions of a suction pulse and a blowing pulse. The fuel pumping capacity of the oil pumping unit which is connected with the carburetor is greatly increased to improve working stability of the engine. | 07-17-2014 |
