Abstract

1,244,494. Valves. SOC. ANON. FRANCAISE DU FERODO. 11 Oct., 1968 [13 Oct., 1967], No. 48281/68. Heading F2V. A valve has a deformable closure member 2 movable relative to two seats la, 1b by a manually or thermostatically operated lever 8 which moves vertically on rotation due to the co-operation of two sets of three pins 10a, (11a), (12a), 10c, (11c), (12c), at different radial distances from the axis of rotation with two sets of three arcuate ramps 10, 11, 12, 10b, 11b, 12b at correspondingly different radial distances formed respectively on a valve body cover 14 and two platforms 9, 17 rotatable with valve stem 7. The closure surface is frusto-conical adjacent its periphery so that it contacts first seat 1a and after subsequent deformation seat 1b. The members on which the pins and ramps are formed may be interchanged. In a modification a platform on which pins or ramps are formed is rotatable between a cover and a platform having co-operating ramps or pins thereon and secured to the valve body. The closure member surface is flat and co-operates with a pair of seats of different height. In a further modification, a diaphragm spring biases the closure member upwardly and a single rotatable platform with pins co-operates with a cover with corresponding ramps.
