Abstract
An inlet valve having a shortened lifting lever mechanism includes a main body having defined therein a compression hole and a waterway passage; a sealing pad; a float; and a shortened lifting lever mechanism that is rotatably connected to the main body, that comprises at least two lever stages each having a fulcrum, respectively, and that include a first stage lever, and a last stage lever that are connected in a driving way. The float is coupled to the first stage lever so that a dynamic body is formed to drive the shortened lifting lever mechanism to move. The sealing pad is assembled to the last stage lever so that the sealing pad opens or closes the compression hole with the movement of the shortened lifting lever mechanism when the float moves up and down. A method of shortening a lifting lever mechanism of an inlet valve is also disclosed.
