<p>A valve (10) and an inhalator with the valve are disclosed. A valve case (12) is secured to a container (11) storing pressurized fluid. A valve pin (13) is moveably mounted to the valve case. First (17) and second (23) seals are arranged in a spaced relation in an axial direction of the valve pin. The first seal is mounted onto a piston portion of the valve pin that is received in the valve case and exposed to the pressurized fluid. The valve pin is formed with a fluid passage (19) having an outlet communicating with outside of the container and an inlet (20) communicating with a space between the piston portion (13b) and the valve case and arranged between the seals in a spaced relation. The valve pin takes a first position where the first seal cooperates with the valve case to block fluid communication between inside and outside of the container through the space and the fluid passage and a second position where the first seal cooperates with the valve case to establish the fluid communication between inside and outside of the container therethrough.</p> |
