A quick connect coupling having a female part with a throughbore for receiving a tube having an annular extending bead. A latch is supported in the female part in communication with the throughbore. A verifier is provided in stacked arrangement with the latch. Insertion of the tube results in extending sides of the latch expanding outwardly and likewise expanding the extending sides of the verifier. Upon passage of the bead past the latch, the latch seating in the engaged position, with the verifier held open by alignment with the annular bead. The verifier subsequently being displaced to a fully engaged position to indicate that the fluid coupling is fluidly and fully connected.

A plug having a longitudinal axis includes a plug body having a generally flat sealing surface on an axial end thereof, and a protuberance extending from the axial end generally concentric with the longitudinal axis. The protuberance has a first section contiguous with the plug body, and a second section having a hub portion contiguous with the first section and a plurality of generally evenly spaced arms extending outward from the hub portion. An underside surface of each arm faces the sealing surface of the plug body and has a generally flat portion and a ramped nub thereon projecting toward the sealing surface. The plug may be inserted into a compatible socket having tabs and rotated about the longitudinal axis for sealable engagement with the socket.

The present invention provides improved couplings for conduit systems. A male coupling and a female coupling may be mechanically engaged by inserting the male coupling into a receiver in the female coupling until fastening structures are aligned, and then rotating one or both of the male and female couplings until the fastening structures are overlapping and in interfacial engagement. The male and female couplings provide an efficient coupling solution for end-to-end conduit connection and also addresses a leakage problem in conventional irrigation pipe couplers.

Device for supplying pressurized fluid, including a first valve housing an internal fluid circuit, the device including a second valve having an internal circuit and forming a physical entity distinct from the first valve. The first and the second valve including respective coupling members forming a detachable male/female quick-connection system for the second valve on the first valve. The two valves being configured such as to place their internal circuits in communication when the second valve is coupled to the first valve via the quick-connection system.

A coupling arrangement including a first part and a second part that can be selectively coupled and uncoupled. In some examples, the second part includes an internal seal. In some examples, the second part includes a radial flange for momentarily engaging with a safety catch arrangement of the first part when the second part is decoupled from the first part and a fluid pressure within the first internal passageway exceeds a predetermined threshold. In some examples, the second part defines an external groove for accepting ball bearings of the first part, wherein the external groove has a semi-circular shape. In some examples, the first part defines a vent passageway extending from the internal passageway, through a sidewall of a main body part of the first part, and through an interstitial space defined between the sidewall and a sleeve member of the first part. In some examples, the first part includes ball bearings formed from a polymeric material.

A chemical component mixing apparatus for use with a fluid source in creation of a concentrated solution mixture is described. The mixing apparatus includes at least one mixing station. The mixing station includes an injector assembly, where the injector assembly includes at least one venturi chamber having at least one suction port in fluid communication with the at least one venturi chamber. The apparatus also includes at least one super concentrate chemical component housed within a chemical container, where the chemical container is fluidly connected by a first tube to the at least one venturi chamber via the at least one suction port, a receiving container fluidly connected to the injector assembly via a second tube, and a fluid source inlet introducing a fluid into the at least one mixing station, where the pressure within the at least one mixing station is less than 150 psi. The fluid passes through the at least one venturi chamber, thereby drawing the at least one super concentrate chemical component into the venturi chamber, and the concentrated solution mixture is dispensed from the injector assembly into the receiving container.

The present disclosure provides a female connector. The female connector comprises a housing, a retaining clamp and an indicating clamp. The housing defines therein a channel extending in an axial direction and is provided with a housing window. The retaining clamp is arranged around at least part of the housing and can at least partially enter the channel through the housing window to secure the female connector with a male connector. The indicating clamp is arranged around at least part of the retaining clamp and the housing, and is releasably locked to the retaining clamp. The indicating clamp is locked to the retaining clamp when the male connector is received by the female connector but not yet secured in position, and is released from the retaining clamp so as to be removable from the retaining clamp when the male connector is secured in position in the female connector.
