A check valve, including a valve and a valve support surface, to permit a fluid to move through the check valve in a first direction and resist a fluid flow through the valve in a second direction, the valve having a valve diaphragm and an isolating bridge, with a portion of the valve engaging against valve support surface to resist deformation or stretching of the valve when a backflow of fluid into the check valve occurs. The valve support surface having a first surface portion and a second surface portion, and the valve positioned with the valve diaphragm spaced apart from the first surface portion, and the isolating bridge spaced apart from the second surface portion.

A device for limiting or keeping constant a quantity of fluid flowing therethrough, includes: a housing with a front chamber and a rear chamber; a partition arranged in the housing with two or more openings; and a flow limiting element arranged in one or both openings. The flow limiting element includes a housing provided with an inlet, an outlet and a throughflow opening; and a resilient plate-like valve element mounted in the housing, substantially able to close the throughflow opening by resilient movement in the direction of a valve seat arranged in the housing adjacently of the throughflow opening. The valve element is fixed on one side and can move resiliently on the opposite side in the direction of the valve seat. A mould produces one or more injection-moulded products. The injection-moulded product is a flow limiter for limiting the force of the flow of a fluid flowing therethrough.

A mechanical shutdown valve for preventing an over pressure condition is described. A valve body has an inlet, an outlet, and a channel extending from the inlet to the outlet. A valve seat and a diaphragm are positioned in the valve body. The diaphragm controls a fluid flow through the valve body. A mesh is coupled to the diaphragm such that the mesh and the diaphragm separate an upstream portion of the channel from a downstream portion of the channel. The mesh extends from the diaphragm to an inner surface of the valve body and limits fluid flow between the diaphragm and the valve body. A spring biases the diaphragm towards the open position. A characteristic of the spring determines a differential pressure threshold between the upstream portion of the channel and a downstream portion of the channel at which the diaphragm engages the valve seat.

In a flow rate controller unit (1) it is thus provided to generate a temporal profile (22) of a volumetric flow, in which temporal profile (22) a switching profile by way of which at least one flow controller (6) is actuated for varying the defined volumetric flow is run.

A storage container having a base storage compartment configured to receive a divider by which the storage compartment is divided into two or more sub-compartments, wherein divider includes a tool configured to provide a secondary utility or function unrelated to dividing the storage compartment.

A fluid flow regulator (10) comprising: a valve chamber (12) having a fluid inlet (14a) and a fluid outlet (14b); and a valve member (16) inside the valve chamber (12), the valve member (16) moveable inside the valve chamber (12); wherein the valve member (16) is concave in the direction of the fluid inlet and convex in the direction of the fluid outlet.

An apparatus, especially adapted for regulating flow of in-line drip irrigation device emitters. The disclosed apparatus converts high liquid flow to a low flow rate as low as 0.02 gallons per hour. The liquid is introduced at a controlled high flow rate, such as by the use of a pressurized fluid supply conduit. The liquid then flows into a number of inlet inflow gates before traversing a pressure responding diaphragm. The closing pressure response of the pressure responding diaphragm, provided primarily by a number of elastomeric o-rings, must be overcome by the pressurized fluid entering through the inlet inflow gates before transmitting regulated fluid flow through an outlet means, wherein said ancillary elastomeric o-ring is a rubber annular component assembled with a tubular rigid insert prior to insertion of drip line extrusion. The present invention provides an apparatus and method for regulating flow of pressure-responding diaphragms of extruded in-line irrigation device emitters'.

A distributed fuel module includes a fuel pressure vessel with a gas port and a fuel port, a hydraulic circuit breaker connected to the fuel port, and a gaseous circuit breaker. The gaseous circuit breaker is connected to the gas port, is fluidly coupled to the hydraulic circuit breaker through the fuel pressure vessel, and is cooperatively associated with the gaseous circuit breaker to isolate the fuel pressure vessel from a compressed gas header and a fuel header according to pressure differential within the hydraulic circuit breaker and pressure differential within the gaseous circuit breaker. Power modules and methods of controlling fuel flow in fuel modules are also described.
