Abstract: An oil suction propeller structure for a hermetically sealed compressor includes a rotor, a crank shaft pressure-inserted in the rotor, an oil guide piece pressure-inserted in a lower portion of the crank shaft, a lower wing fixedly inserted in the oil guide piece and soaked in an oil, an upper wing having a width thereof wider than that of the lower wing, and an intermediate portion extending from the lower wing and gradually broadening in width toward the upper wing. The oil suction propeller structure improves oil supply capacity, and minimizes a whirling sound and a dropping noise which may occur during the rotation of the oil guide piece and the oil suction propeller thereof, for thereby enhancing reliability of the hermetically sealed compressor.

Abstract: A hand lever apparatus is mountable on a working machine for controlling operation of the working machine. The hand lever apparatus includes a main lever and a magnitude-magnifying mechanism. The magnitude-magnifying mechanism includes a pivot pin, a lever member pivotal about the pivot pin, a pulley, and a connecting cable. The lever member has a shorter arm portion and a longer arm portion, which opposes the shorter arm portion and is operatively connected to a throttle cable of a throttle valve of the working machine. The shorter arm portion is operatively connected to the main lever via the connecting cable so that actuation of the finger-manipulable portion pivots the lever member about the pivot pin and causes the longer arm portion to pull the throttle cable away from the throttle valve and open the throttle valve of the working machine from a minimum-opening idling state.
