Abstract
A valve includes a valve body (1, 2), a tube (3) made of an elastomer extending through the inside of the valve body, and a roller (23) and a pressing surface (14) disposed facing each other across the tube (3). The roller (23) can be brought close to the pressing surface (14) to collapse the tube (3) between the roller (23) and pressing surface (14) and close the flow passage in the tube (3), and the roller (23) can be moved along the tube (3) to make a collapsed position where the tube (3) is collapsed by the roller (23) and the pressing surface (14) move along the flow passage axis of the tube (3) while maintaining the flow passage in the closed state.
Claims12
A valve, comprising a valve body and a tube made of an elastomer extending through the inside of said valve body, and for closing off the flow of fluid in said tube,
- said valve characterized by further comprising squeezing means disposed facing each other across said tube, said squeezing means being adapted so that said squeezing means can be brought close together to collapse said tube and close the flow passage inside said tube and so that at least one of said squeezing means can be moved along said tube so as to move a collapsed position where said tube is collapsed by said squeezing means while maintaining said flow passage in the closed state.
