Abstract: A valve has a valve body, a valve sheet formed in the valve body which contacts the valve sheet in an axial direction, to thereby open and close the valve sheet with a knurling portion and a screwing action. A handle is combined with a handle combination unit formed in an upper portion of the valve body, so that a valve rod can ascend and descend. An oil storage chamber is located between the knurling portion and the screw, to maintain the ascending and descending of the valve rod. The angular slope in the screw thread is formed so as open and close the valve by 90° rotation of the valve rod. A stem contacts the valve sheet, the stem having a conical end portion, which is received by the valve sheet. The handle is flexibly manipulated to simply and swiftly control flow and entrance/exit of fluid. The valve can be used semi-perpetually since wear of the valve sheet is prevented, providing excellent general purpose usability.

Abstract: The present invention relates to a device for driving a sprocket of a bicycle, which enables a rider to easily rotate both pedals even with little force when both cranks of the pedal are vertically positioned. According to the present invention, when a crank (11) gets to be vertically positioned by rotating the pedals (11a), a guide pin (21) projected from a rotating plate (20) draws a tensile spring (41) from the guide groove (31) and thereby the rotating plate (20) gets to be elastically rotated so the crank (11) can go off the vertical position rapidly. Accordingly, the rider can easily rotate the pedals, and at the same time, the force of restitution of the drawn tension spring (41) can help the sprocket (10) be rotated. Consequently, the accumulated force of the tensile spring (41) accelerates the rotation of the sprocket (10) to enable the crank (11) to go off the vertical position effectively, which in turn enables the rider to drive the bicycle with ease.
