摘要： There is disclosed a fluid supply valve comprising a disc-shaped valve body which is equipped with a fluid supply port in the central portion thereof and composed of an elastic material whose peripheral portion is reinforced and fixed with a rigid material, the fluid supply port being closed when the valve body abuts against a fixed valve seat placed so as to be opposite to the fluid supply port, and being opened when the valve body is separated from the fixed valve seat, wherein the disc shaped valve body is equipped further with a thin walled portion in the intermediate annular portion between the fluid supply port and the peripheral portion in the radial direction, and/or with an inflectional portion in the radial direction between the fluid supply port and the peripheral portion. According to the above constitution, it is made possible to minimize the reaction force at the time of the deformation of the valve body and thus to provide an ink tank valve capable of favorably supplying a recording head with a proper amount of ink.
