ABSTRACT:
A pinch valve has a tubular resilient sleeve with at least one transversely elongate aperture extending through it that is opened and closed by a control member having elements engaging diametrically opposite regions of the sleeve. The control member is rotatable on the sleeve between one angular position in which said elements engage regions of the sleeve substantially co-incident with the transverse longitudinal axis of said aperture to hold the aperture open, and another angular position in which the elements engage opposite regions transverse to said axis to squeeze said aperture closed.
