Abstract:
In a throttle device, a needle member (20) includes a tapered portion (20P) having a taper angle (2θ), and a length (X) along a center axis from a position (20PS) to an apical surface of the tapered portion (20P) is set to a value equal to or above a prescribed amount of lift (L′×cos2 θ), where the position (20PS) is a position corresponding to an edge (22as) of a valve port (22a) in a state where the tapered portion (20P) is inserted in the valve port (22a) and establishes a closed state of the valve port (22a).
