text: defining a valve element sealingly engageable with the adjacent valve seat, the length of said valve rod being substantially equal to the distance between said valve seats so that when one element sealingly engages its adjacent valve seat, the other valve element is spaced from its adjacent valve seat; said diaphragms having openings therethrough whereby fluid pressure within the respective chambers will act on both sides of the diaphragm therewithin; said housing having three ports extending therethrough, one of said ports communicating with said passageway and the other two ports communicating respectively with the respective chambers at a location therein close to the adjacent valve seat and between the diaphragm and the adjacent end of said passageway; and axially movable actuating means extending through the remote end of one of said chambers and continuously engaging at least one of said valve rod and the diaphragm therewithin for moving said valve rod axially and thereby flexing said diaphragms.
text: Avalve construction, comprising: an elongated housing, said housing including means defining a pair of longitudinally spaced chambers, said chambers being closed at their remote ends; a passageway connecting the adjacent ends of said chambers, said passageway being of smaller cross-sectional area than said chambers and having oppositely facing valve seats formed at the ends thereof; said housing having three ports formed therein, one of said ports communicating with said passageway and the other ports communicating respectively with the respective chambers; a solid inextensible valve rod extending through said passageway and beyond the axial ends thereof into said chambers, said valve rod being of smaller cross-sectional area than said passageway and defining therewith a zone through which fluid may flow between said chambers and said one port; a flexible diaphragm within and extending transversely across each of said chambers and mounted on said housing for flexing movement toward and away from the other chamber, said flexible diaphragms being connected to said valve rod and meansv on said valve rod and each said diaphragm,

text: Avalve construction, comprising: an elongated housing, said housing including means defining chamber means, said chamber means being closed at one of its ends; a passageway connected to the other end of said chamber means and extending longitudinally in said housing, said passageway being of smaller cross-sectional area than said chamber means, said passageway having valve seat means facing said chamber means; said housing having ports therein, one of said ports communicating with said passageway and another of said ports communicating with said chamber means; flexible diaphragm means within and extending transversely across said chamber means and mounted on said housing for flexing movement toward and away from said valve seat means; means on said diaphragm means defining valve member means sealingly engageable with said valve seat means; said diaphragm means having openings therethrough whereby fluid pressure within said chamber means will act on both sides of said diaphragm means; and an axially movable actuating means extending through the remote end of said chamber means and permanently engaging said diaphragm means and being disposed coaxial with said valve member means, said valve member means and said actuating means being imperforate so that fluid can flow into said passageway only when said valve member means is spaced from said valve seat means.
