A maintenance operation support device includes a procedure information outputter configured to output procedure information representing an operation procedure of maintenance operations for a facility, the procedure information being obtained by combining action definition information for defining actions of a setting tool that adjusts or sets the facility and operation definition information for defining operations to be instructed to a maintenance operator who performs the maintenance operations for the facility.

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.

The present invention includes a lateral support member for a server computer constructed to permit advantageous airflow. The present invention can be operated to shunt organized airflow into multiple computer cases and/or organized airflow from multiple computer cases to a dedicated heat reservoir.

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 flow path switching valve is used in an engine water cooling system mounted on a mounting surface of an engine, and switches a flow path of a cooling water in the engine water cooling system. The engine water cooling system has a block jacket formed on a cylinder block and a head jacket formed on a cylinder head, connected to each other via a communication passage. The cooling water flowing in from an inlet of the block jacket flows into an inlet port of the flow path switching valve from an outlet of the head jacket via the communication passage. An inflow barrier plate is provided, which closes a part of a leak path side of the inlet port to suppress an inflow of the cooling water from the block jacket via a leak path made in the cylinder block and the cylinder head.

A mixing valve includes a housing having, arranged therein: a first flow duct having a first flap mounted rotatably in the first flow duct and configured to influence the throughflow cross section of the first flow duct, and a second flow duct, the second flow duct issuing into the first flow duct, and having a second flap mounted rotatably in the second flow duct and configured to influence the throughflow cross section of the second flow duct. The first flow duct has, downstream of the issue of the second flow duct, as seen in the flow direction, a region with at least two cross-sectional widenings, and at least one stationary guide element, projecting into the first flow duct, is arranged in the region with the at least two cross-sectional widenings.
