Abstract: A vacuum demand valve for delivering a flowable material is disclosed. The valve has a housing having a proximal end, a distal end, an intermediate segment therebetween defining a passageway wherein the flowable substance can flow from the proximal end to the distal end. The housing can be a tubing. A valve member is located along the intermediate segment. The valve member has a closed condition wherein the flow of the flowable material from the proximal end to the distal end is stopped and an open condition wherein the flow of the flowable material from the proximal end to the distal end is unstopped. The valve member is biased in the closed condition and is responsive to a partial vacuum provided by the user through the passageway for placing the valve member in the open condition.

Abstract: The present invention relates to a light weight check valve for use in bulk material transfers that incorporates a smooth, generally spherical interior cavity to minimize flow inefficiencies. The check valve is made from two portions: a body portion and a lid assembly which is removably mounted to the body portion. The gate valve, or poppet, is hingedly mounted to the lid assembly. Hence, when the check valve assembly is opened for inspection, by removing the lid assembly, the poppet is removed along with the lid assembly, to allow for easy inspection of the poppet.

Abstract: A check valve has a valve body with an annular seat surrounding the duct and a flap member pivotally mounted on the valve body so as to pivot about an axis transverse to the duct from an open position to a closed position pressing against the seat. The flap member includes a circular flap plate with a rigid backer plate and a front resilient layer carried on a pivot mounting bracket having a rigid mounting plate generally parallel to the backer plate. The backer plate and the mounting plate each have a central hole therethrough and are connected by an integral body molded from a resilient elastomeric material to form the front resilient layer, a back stopper portion and a connecting neck portion arranged so as to provide resilient flexing movement between the flap plate and the mounting bracket. The mounting bracket is carried on a shaft with a pair of coil springs housed in a receptacle separated from the duct so that broken spring parts do not enter the fluid in the housing.

Abstract: A poppet valve assembly is provided for use on a fuel tanker truck which enables the truck's driver to determine whether fuel is flowing through the valve assembly and whether fuel is present in the valve assembly. When a threshold flow rate through the valve assembly is reached, fluid flows inside a flow channel. The flow channel has a fluid indicator and a flow indicator therein mounted in a sight glass. When fluid is flowing in the flow channel both indicators rise. When fluid is present but not flowing in the flow channel only the fluid indicator rises. The fluid and flow indicators, being different colors, may be easily seen at a distance.

Abstract: A fitting structure for attaching a fuel pump in a fuel tank, which includes a gasket surrounding a pump insertion hole of the fuel tank. The gasket is collapsed by a presser ring through a flange portion of the fuel pump, thus enabling the gasket to provide an effective seal between the fuel pump and the fuel tank. A nut fastened onto a bolt is used to bring a second valley portion of the presser ring into close contact with a first mount portion of a fixed side ring that has been preliminarily welded to the fuel tank, thus securely fitting the fuel pump to the fuel tank. As compared with a conventional fitting structure using a bayonet or snap fit connection, wherein the fitting structure must be turned against the gasket to be fitted into a secure position, this new fitting structure presses the gasket into place, thus avoiding the turning motion and the resulting damage that may be caused to the gasket.
