  • Springless diaphragm valve
    Patent number: 4244554
    Abstract: A valve having a flexible diaphragm for opening and closing the valve. The diaphragm is biased into valve-closing position by a ridge, formed in the valve body, which presses the diaphragm toward the valve seat. A rigid backup washer is secured to the diaphragm solely by an elastomeric type adhesive. A bleed hole in the diaphragm establishes communication between the valve inlet port and a chamber on the side of the diaphragm opposite the valve seat. The bleed hole is in the margin of the diaphragm which is sandwiched between two portions of the valve body.
