Plumbing fitting assemblies are described. The plumbing fitting assemblies use a male and female fitting combination that enables a user or installer to make a sealed connection on an internal diameter of a female part or receiving end by way of an o-ringed shank on a male part or insert end. A connecting device is rotatably attached to the male end. The connecting device also engages to an outer surface of the female part such that the sealed fitting assemblies will not disconnect under normal pressure of a fluid or air working through the assemblies.

A valve for installation in a valve bore of a housing or valve block includes a valve bushing for insertion into the valve bore, a guided valve piston that can be moved axially in the valve bushing, an activation section of said piston projecting above the valve bushing axially, and a valve cover that is configured to be arranged over the valve bore and that forms, together with the activation section of the valve piston, at least one activation pressure chamber.

A simplified and downsized coupling position switching mechanism capable of transmitting reliably and smoothly the driving force of the drive unit to the slide metal frame to switchably change a coupling position between the slide metal frame and the drive unit in the sliding nozzle apparatus. A coupling portion in the slide metal frame protrudes on the side of the drive unit and allows a rod head of the drive unit to be coupled thereto, and the coupling portion has a coupling space allows the rod head to be disposed movably in a sliding direction of the slide metal frame. A separator is inserted into the coupling space to divide the coupling space into first and second coupling chambers in the sliding direction of the slide metal frame. The coupling portion has a fitting section for allowing the separator to be fitted thereinto when it is inserted into the coupling space.

A fill valve assembly for a toilet tank is described. The fill valve assembly includes a two part design. The fill valve assembly includes a fill valve that connects or engages with a shank. A connection between the fill valve and the shank is located in an interior of the tank, which is easily accessed. The fill valve may be easily replaced by disconnecting the fill valve from the shank.

A substrate block for a fluid delivery system is provided, the substrate block having an upper surface. The upper surface has an inlet substrate port and an outlet substrate port formed into the upper surface. A substrate fluid passageway extends from the inlet substrate port and the outlet substrate port. The substrate fluid passageway extends in a smooth arc which is free of corners or angular walls.

A valve actuation system includes a drive device, equipped with an axial extension, which includes an actuating drive with a drive output side intended for coupling with a valve and an axial rear side opposite this, wherein the actuating drive has on its axial rear side a mounting interface for the attachment of an auxiliary device which interacts with the actuating drive wherein, in order to allow attachment of the particular auxiliary device which is to be mounted, or which is mounted, the mounting interface of the actuating drive is equipped with several different attachment devices which differ in their attachment possibilities and which can be used selectively. In this way, a high degree of variability in the attachment of auxiliary devices is provided.

An adjustable operating rod assembly is provided. In one embodiment a telescoping rod and tube are provided such that the length of the operating rod can be selectively adjusted in order to accommodate fluid inlet pipes of various lengths and regardless of manufacturer.

A method of manufacturing a substrate block for a fluid delivery system is disclosed. First, a mold is provided, the mold having a cavity. The cavity of the mold is filled with a fluoropolymer to form a substrate block having an upper surface. A curved insert is withdrawn from the cavity to form a substrate fluid passageway extending from an inlet substrate port to an outlet substrate port. The substrate fluid passageway extends between the inlet substrate port and the outlet substrate port in a smooth arc free of corners or angular walls.

A method of processing semiconductors using a fluid delivery system is disclosed in which seal inserts are utilized to fluidly connect an active component that bridges two substrate blocks.

A valve housing assembly includes a valve housing and a hollow cover. The valve housing includes an upper portion configured to couple to a valve cartridge and a lower portion configured to couple to one or more water supply lines. The hollow cover is configured to be coupled to the valve housing in a plurality of different orientations, and substantially surrounds, and sealingly engages, the valve housing. The valve housing assembly is configured to be coupled to, and received within, a plurality of faucets having different configurations.
