Abstract
The invention contemplates a check-valve construction wherein a plurality of at least three generally triangular valve members are independently hinged to the respective base lines of a pyramidal seat configuration, the base lines being in a plane which essentially establishes the upstream end of the valve, and the apex of the pyramid (and, thus, the apex of each valve-member triangle) essentially establishes the downstream end of the valve.
