A heating system can include certain pressure sensitive features. These features can be configured to change from a first position to a second position based on a pressure of a fuel flowing into the feature. These features can include, fuel selector valves, pressure regulators, burner nozzles, and oxygen depletion sensor nozzles, among other features.

A backflow prevention device with reduced pressure zone to be installed in water systems is provided and comprises a body provided with inlet, outlet and exhaust openings, a check assembly with a stem, an elastic element, and a plate, a mobile diaphragm or membrane adapted to interrupt the fluid connection between the outlet opening and inlet opening and between said inlet opening and exhaust opening, wherein said stem of said check assembly is stabilized with respect to said body, and said plate is slidably disposed along the stem and is cooperatively placed with the mobile diaphragm or membrane in order to interrupt the fluid connection between said inlet opening and said outlet opening.

A valve unit for regulating the flow of working fluid between a working chamber of a fluid working machine and both a first working fluid line and second working fluid line, the valve unit comprising: a first valve comprising a first valve member and one or more cooperating first valve seats, a second valve comprising a second valve member and one or more cooperating second valve seats, an actuator coupled to both the first and second valve members through which a force may be applied to urge the first valve member open or closed and to urge the second valve member open or closed, a coupling between the actuator and the first valve member, wherein the coupling between the actuator and the first valve member comprises a connector which extends at least partially through the second valve member.

Embodiments of the present application provide better configurations of a partition-attached metal pipe as an external cover material for a wire harness, including: a metal pipe through which a wire harness including a plurality of electrical wires can be inserted; and a separate metal partition member that is to be assembled by being inserted into the pipe; wherein a plurality of electrical wire insertion spaces that are partitioned by the partition member and a circumferential wall of the pipe are provided continuously in an axial direction of the pipe.

The present invention relates to a cartridge for an electronic tap having a handle or controller with an extended operative range of motion, which allows moving said handle or controller beyond its normal range of motion determined by a first stop, providing in said extended areas additional functionalities using a control system that determines the position of the handle in order to associate to said position a flow value, a fluid mixing ratio value, and/or an additional functionality. The invention also relates to the tap including said cartridge with a handle having an extended operative range of motion and to the operation method thereof.

A faucet includes a mixing chamber, a bypass chamber, a hot water actuator, a cold water actuator, and a valve assembly. The mixing chamber is in fluid communication with a spout. The bypass chamber is operably coupled to a source of cold water. The cold water actuator is operably coupled to provide, upon actuation, cold water to the mixing chamber. The hot water actuator is operably coupled to provide, upon actuation, hot water to the mixing chamber. The valve assembly has a seal configured to move in a direction away from the spout responsive to a temperature of water in the mixing chamber exceeding a threshold, such that fluid connection is provided between the bypass chamber and the mixing chamber.

A flush-mounted group for mixing water for a bathroom or kitchen, comprising: a body comprising a valve, designed to be installed in a seat having a given depth with respect a finished surface, a fastening means for fixing the body to the seat, which is adjustable on the body to set the depth at which the body is inset inside the seat, a plate mountable on the finished surface to enclose the body inside the seat and which is provided with an opening for accessing the body, a control member for operating the valve, which is connected to the valve through the opening of the plate. The mixing group comprises a coupling means for connecting together the valve and the control member, which can be adjusted so as to vary a distance between the control member and the valve and ensure correct positioning of the control member inside the opening.
