A diaphragm type flush valve for use with toilet devices such as urinals and water closets that includes a valve member, a diaphragm, a guide member extends downwardly from the diaphragm, and a disk positioned on top of the diaphragm. The disk is threadably attached to the guide member and functions to secure the diaphragm, the disk, and the guide member into the valve member. The disk includes a rigid body made of a composite material and a seal member made of an adhesive and a thin layer of rubber, with the seal member having a portion on an upper surface of the disk for sealing contact with a relief valve. The disk also includes a plurality of spaced protrusions and inwardly directed on its upper surface in order to add accuracy and stability to the diaphragm assembly.

A method for securing a toilet tank to a toilet bowl through an attachment assembly. The method includes the steps of engaging a valve to the tank through an opening in the tank, moving a mounting bracket over the valve through an opening in the mounting bracket to position the mounting bracket adjacent to the tank, the mounting bracket having at least three mounting locations with fasteners attached thereto, coupling a valve nut to the valve to secure the mounting bracket between the tank and the valve nut, and securing the mounting bracket to the bowl through the fasteners. The at least three fasteners are disposed external to the tank and couple the tank to the bowl without directly engaging the tank.

The present invention's goal is to devise an apparatus (here-forth called punch-ball) made of a tension-reversible membrane that will assume a particular three-dimensional predetermined shape when under tension, apparatus that will border a central empty space, central space limited by the interior face of the membrane, and central space that will be in direct communication with the exterior space outside of the external face of the punch-ball through orifices in the membrane (here-forth called punches), punches that will not decrease the ability of the membrane to exhibit a tension force. The punch-ball can be used freestanding or in connection with an object representing a confined space that will be abutting the exterior face of the punch-ball when the punch-ball is under tension. The punches will allow fluid to flow freely or solids to be transferred freely between the interior and exterior of the punch-ball membrane without any limitations to the initial flow through the cavity prior to the punch-ball membrane being deployed in the cavity, the interior face of the membrane being defined as surrounding the empty space inside the punch-ball while the exterior face of the membrane as facing the exterior of the punch-ball. The membrane will be provided with hinge borders (borders that will lack completely or partially the property of being under tension, and at same time have various degrees of elasticity or deformability), borders that will allow the punch ball shape to adapt to the shape of the cavity in which it will be deployed, or for the action to be undertaken. At the end of the action performed the tension in the membrane will cease, the punch-ball will be un-deployed and then removed from the location of action.

A plastic water channel main body of a temperature adjustable water tap includes a plastic H-shaped frame and a water sealing plate. A water outlet leading upward is disposed in the middle of a transverse pipe of the frame. Two ends of the transverse pipe are connected to valve seats protruding upward. An inner hole of the transverse pipe enables the water outlet to communicate with inner cavities of the two valve seats. The bottom of each valve seat is provided with a water inlet and a water inlet pipe extending downward. Each water inlet pipe communicates with the water inlet of the corresponding valve seat. The front of the transverse pipe is provided with a channel communicating with the inner hole and cutting into the inner cavities of the two valve seats. The water sealing plate is fixed on the opening of the channel and seals the channel.

An apparatus and method for mounting and inflating tires is described that is suitable for quickly sealing the beads of a tire to the rim of a wheel. The present invention delivers a high volume of pressurized air to an interior of a tire through a nozzle. The apparatus of the invention is particularly well suited for tire changing machines and tire mounting subsystems. The apparatus includes a tire changing station, an air supply controller, and a nozzle capable of delivering a high volume of pressurized fluid into an interior of a tire through a valve stem hole of the wheel rim.

In some implementations, an apparatus includes a container having an exterior surface, having an interior surface and having a defect, a gasket positioned over the defect in the container, the gasket having a length, a width and a depth, a rigid patch positioned over the gasket, a plurality of pairs of studs and nuts positioned near the outer perimeter of the rigid patch, the studs being friction welded to the exterior of the container.

A valve in which the flow control element includes a fixed disk and a rotatable disk, and a motor operable to rotate the rotatable disk. The motor is disposed in the bore of the valve, aligned with the long axis of the valve body and the axis of rotation of the rotatable disk.

A human-powered pump assembly includes a frame and a treadle pivot attached to the frame, such that the treadle pivot defines a horizontal rotational axis. The pump assembly includes a pair of treadles coupled to the treadle pivot and a rocker pivot attached to the frame, such that the rocker pivot defines a separate horizontal rotational axis. The pump assembly includes a reciprocating rocker coupled to the rocker pivot and to the pair of treadles to constrain the motion thereof, such that the rocker pivot axis is located below the treadle pivot axis.

A reed valve module includes a module body and a reed petal. The module body includes a seating surface located on a first side of the module body and a sealing face located on a second side the module body. The reed petal is positioned adjacent to the second side of the module body and adapted to seal against the sealing face when the reed petal is in a closed position, wherein the reed valve module is a self-contained modular unit that is adapted to be inserted into a receiving cavity of a modular reed valve assembly such that the seating surface is positioned adjacent to a retaining surface of the modular reed valve assembly and an interfacing surface of the reed valve module is positioned adjacent to a second retaining surface of the modular reed valve assembly, and wherein the reed valve module is adapted to be captured and retained within the modular reed valve assembly between the first and second retaining surfaces.
