A heat dissipating fan includes a housing having a base and a sidewall coupled to the base. The sidewall defines a compartment. The housing further includes an air inlet, an air outlet, and a dust channel. The air inlet, the air outlet, and the dust channel are in communication with the compartment. A stator is coupled to the base of the housing. An impeller is rotatably coupled to the stator. A control element includes a driving circuit electrically connected to the stator and a rotating direction control circuit electrically connected to the driving circuit. In another embodiment, the heat dissipating fan includes a housing having a base and a lateral wall coupled to the base. The lateral wall defines a compartment. The lateral wall includes an air inlet and an air outlet both in communication with the compartment. The air inlet also acts as a dust channel.

This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one example, a valve leakage test may be performed on a valve assembly including a valve body with a first valve and a second valve, where the valves may be positioned across a fluid path in the valve body with an intermediate volume between the valves. A pressure sensor may be in fluid communication with the intermediate volume and may sense a measure that is related to the pressure in the intermediate volume. The pressure sensor may communicate with a controller to determine a measure that is related to a pressure change in the intermediate volume and compare the measure that is related to a pressure change to a first and/or second threshold value. The controller may output a signal if the measure meets and/or exceeds the first and/or second threshold value.

Gas valve with valve leakage test

This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one example, a valve assembly may be configured to perform a valve proving test as part of an operational cycle of a combustion appliance coupled to the valve assembly. The valve assembly may include a valve body having a fluid path, first and second valve sealing members translatable between an opened position and a closed position, and one or more pressure sensors in fluid communication with an intermediate volume of the fluid path between the first and second valve sealing members. A valve controller may be in communication with the pressure sensor and may monitor a measure related to a pressure change rate in the intermediate volume. The valve controller may then output a signal if the measure related to a pressure change rate in the intermediate volume meets and/or exceeds a threshold value.

Gas valve with electronic valve proving system

This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one illustrative but non-limiting example, a valve assembly may include a valve body having an interior and an exterior, a valve or valve sealing member positioned in the valve body, a sensor element (e.g., a magnet and/or a ferrous core) secured relative to the valve sealing member and a sensor (e.g., a magnetic field sensor) positioned outside of the interior of the valve body. The valve sealing member may be movable between an opened position and a closed position, and the sense element may move with the valve sealing member. The sensor may be configured to detect a position of the valve sealing member and communicate that position to a valve controller.

Gas valve with electronic proof of closure system

This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one example, the valve assembly may include a valve body with an inlet port, an outlet port, and a fluid path extending between the inlet and outlet ports, one or more valves situated about the fluid path, one or more valve actuators for selectively moving respective valves, one or more sensors for sensing one or more parameters within the fluid path, and a controller secured relative to the valve body and in communication with the one or more sensors for determining one or more valve assembly conditions based on the one or more sensed parameters. Illustratively, the controller may be configured to communicate information from the valve assembly to a combustion appliance controller that is located remotely from the valve assembly through a communications interface of the controller and across a communications bus.

An equipment fan has a housing ( 22 ) that externally defines an air passage opening ( 41 ) provided in the fan ( 20 ). The fan has a motor ( 21 ) for rotatably driving blades ( 40 ) about a rotation axis ( 23 ), as well as a carrier element ( 51 ), provided between the motor ( 21 ) and the housing ( 22 ), which extends transversely to the passage ( 41 ) and is configured as a trough ( 53 ) that serves to receive an electrical lead ( 52 ) and guides the lead along a predetermined path from the motor ( 21 ) to a location ( 64 ) on the housing ( 22 ). The fan also has a deflection device ( 50 ) which, by deflecting the lead ( 52 ) at a first deflection location ( 55 ) and at a second deflection location ( 84 ) and in at least two planes extending at a predetermined angle with respect to one another, effects strain relief for the lead ( 52 ) that proceeds to the motor ( 21 ).
