Abstract: An air valve includes a valve body having an air passage and a transverse bar suspended in the air passage, a valve flap coupled to said transverse bar at a bottom side to close said air passage, and a movable plate coupled to locating blocks at said transverse bar at a top side and moved vertically between a first position where the movable plate is released from the valve flap and the air passage is closed by the valve flap, and a second position where the valve flap is deformed by the movable plate to open the air passage for letting air pass.

Abstract: A hand pump includes a cylindrical casing having a top open side covered with a top cover and a bottom side provided with an air outlet, a handle inserted through a hole the top cover, and a piston moved with the handle up and down to pump air out of the cylindrical casing through the air outlet, wherein the handle has multiple peripheral sides and angles defining a plurality of longitudinal grooves equiangularly spaced around the periphery for guiding outside air into the cylindrical casing evenly upon an up stroke of the handle, and a wedge-like coupling rod at a bottom end thereof press-fitted into a coupling hole at the piston for enabling the piston to be reciprocated with the handle.
