Abstract: A vacuum demand valve (10) is capable of delivering a flowable material. The valve (10) has a housing (11) having a proximal end (14), a distal end (16), an intermediate segment (18) therebetween defining a passageway (24) wherein the flowable substance can flow from the proximal end (14) to the distal end (16). The housing (11) can be tubing. A valve member (20) is located along the intermediate segment (18). The valve member (20) has a closed condition wherein the flowable material from the proximal end (14) to the distal end (16) is stopped and an open condition wherein the flow of the flowable material from the proximal end (14) to the distal end (16) is unstopped. The valve member (20) is biased in the closed condition and is responsive to a partial vacuum provided by the user through the passageway (24) for placing the valve member (20) in the open condition.

Abstract: A vacuum demand valve for delivering a flowable material is disclosed. The valve has a housing having a proximal end, a distal end, an intermediate segment therebetween defining a passageway wherein the flowable substance can flow from the proximal end to the distal end. The housing can be a tubing. A valve member is located along the intermediate segment. The valve member has a closed condition wherein the flow of the flowable material from the proximal end to the distal end is stopped and an open condition wherein the flow of the flowable material from the proximal end to the distal end is unstopped. The valve member is biased in the closed condition and is responsive to a partial vacuum provided by the user through the passageway for placing the valve member in the open condition.
