A valve is described comprising: an outer sleeve having a radially oriented aperture; a rotatable intermediate sleeve disposed coaxially within the outer sleeve and having a radially oriented aperture being generally aligned with the outer sleeve aperture when the intermediate sleeve is in a prescribed rotational position; means, coupled to the intermediate sleeve, for rotating the intermediate sleeve within the outer sleeve; an inner sleeve disposed coaxially within the intermediate sleeve, defining a chamber with an upstream end and a downstream end, and having a radially oriented aperture being generally aligned with the outer sleeve aperture; means for sealing the upstream end of the inner sleeve so that a fluid medium exiting the chamber flows through the downstream end thereof; and unidirectional flow means having an inlet end in fluid communication with the downstream end of the chamber and an outlet end for the discharge of the fluid from the unidirectional flow means, the unidirectional flow means including means for impeding a flow from the outlet end toward the inlet end to a substantially greater extent than a flow from the inlet end toward the outlet end.
