An aircraft with at least one engine system, at least one zone for ejection of debris originating from the engine system and at least one fluid supply circuit. The latter comprises a shutter configured to occupy open and closed states, at least one return element configured to push the shutter to the closed state and at least one control positioned at least partially in the ejection zone and configured to hold the shutter in the open state against the return element. When the control is broken in the case of an accident, it no longer holds the shutter, which switches automatically to the closed state.

A pressure measuring system is provided in which a closing element supported in the pressure fitting channel is activated or displaced by a pressure surge or a pressure wave and thereby seals the channel to the measuring element and thus prevents an outflow of the fluid.

A water leak detection and prevention device comprised of a leak detection apparatus positioned near a water-dependent appliance to monitor for moisture due to a leak, and a leak prevention system connected to the leak detection apparatus in fluid communication with a water pipe attached to the water-dependent appliance and positioned in-line with the water pipe is disclosed.

A failsafe valve system configured to bring the valve to a predefined state (e.g., fully opened, fully closed) if the actuator fails (e.g., loss of power). The failsafe system of the present disclosure is energy efficient and reliable.

A safety valve device as for use with a compressed gas cylinder and/or a control valve comprising a housing unit, a plug with controlled bleed off channels bored into the plug, an actuator, and an actuating rod, which is designed to engage in the event that a control valve is severed from a compressed gas cylinder, at least partially sealing the opening formed in the compressed gas cylinder from the severing of the control valve, and achieving a safer, controlled bleed off of the compressed gas contained therein.

In one aspect, a wheel hub assembly including a wheel hub body having an interior, bearing assemblies to rotatably connect the wheel hub body to a spindle, and a vent associated with the wheel hub body that opens to the interior of the wheel hub body. The wheel hub assembly further includes an inertia-controlled valve of the vent rotatable with the wheel hub body. The inertia-controlled valve is configured to open in response to rotation of the inertia-controlled valve with the wheel hub body and permit air to flow out of the interior of the wheel hub body.

An electric working machine may include: an electrical component; a first space in which the electrical component is disposed; a partition wall separating the first space from a second space different from the first space, the partition wall including a first communication opening communicating the first space and the second space; and a first one-way valve disposed at the first communication opening.

An orientation valve, in accordance with various embodiments, is disclosed herein. The orientation valve may comprise a first coupling portion, an insert portion, a second coupling portion, an internal cavity, and a piston. The insert portion may have a first inlet aperture and a second inlet aperture. The second coupling portion may be disposed between the first coupling portion and the insert portion. The internal cavity may be coupled to the first inlet aperture and the second inlet aperture. The piston may be disposed within the internal cavity. The orientation valve may be configured to block fluid flow from a compressed fluid source when an evacuation system is in a stored position. The orientation valve may be configured to fluidly couple the compressed fluid source and the evacuation device when the evacuation system is in a deployed position.
