ABSTRACT:
A pinch valve for selectably controlling flow of fluid through one of two resiliently deformable tubes used e.g., for transporting water in a steam iron. The valve comprises a body member defining a compression surface supporting each one of the tubes. A selector lever is pivotally mounted on the body for selectably moving an integral cam abutment between individual tube shut-off positions. A rocker element supported on the tubes is captively held in the body member intermediate the selector lever and the compression surface for rocking movement between tube pinching positions. The cam abutment continually presses on the rocker causing the rocker to bear upon each one of the tubes on the compression surface. As the selector lever is pivoted, the cam abutment engageably slides along the rocker to rock the rocker between its tube pinching positions. The tubes are thus isolated from sliding contact with the cam abutment by the interposed rocker thereby preventing frictional wear of the tubes.
