ABSTRACT:
A device including a valving mechanism which can be operated by one hand, the device includes a housing which surrounds a resilient block of material. The housing may be squeezed to depress and deform the resilient block. Passageways extend through the resilient block to conduct liquid therethrough. A first passage includes a solid valve positioned therein. Compression of the resilient block causes displacement of the valve and distortion of the block material to break the seal around the valve. Additional material is provided strategically in this first passage to insure against leaks from system overpressure. A second passage includes a capillary to allow continuous low volume flow not controlled by an operator.
