An electro-pneumatic valve assembly includes a valve having a valve housing and a poppet and a solenoid valve having an actuator housing and a valve body. The valve housing has a wall that defines a valve inlet that is arranged to receive a fluid flow from a pressurized container and defines a valve outlet and a first port. The poppet is disposed within the valve housing and is movable between a first position and a second position. The actuator housing defines an opening. The valve body has a first wall that defines an inlet that is fluidly connected to the first port and a second wall that defines an outlet that is fluidly connected to the second port.

An inline for an inflatable assembly may comprise a first end defining a primary gas inlet and a second end defining a primary gas outlet. An internal surface may define a flow path extending from the primary gas inlet to the primary gas outlet. An orifice may be located between the first end and the second end. The orifice may be defined, at least partially, by a radial wall extending from the internal surface to the external surface. The orifice may be configured to entrain ambient air with a primary gas flowing from the primary gas inlet to the primary gas outlet.

A slide for an evacuation system may comprise an inflatable slide rail structure. An aspirator may be fluidly coupled to the inflatable slide rail structure. An aspirator retention strap may be coupled between the aspirator and the inflatable slide rail structure. The aspirator retention strap may comprise an elastic material. The aspirator retention strap may be configured to stretch when a predetermined internal pressure threshold of the inflatable slide rail structure is exceeded.

An escape system comprises a slide for facilitating evacuation of from a structure to water, wherein the slide comprises at least one helical inflatable path. The or each helical inflatable path may be configured to extend generally vertically between the structure and the water. The slide may comprise a plurality of helical inflatable paths. The slide may comprise spacing means for controlling the pitch between helix turns of the or each of the helical inflatable paths. A bowsing arrangement for the slide is also disclosed.

A valve assembly for an inflation system that includes a pressure relief valve and a vent valve. The pressure relief valve has a pressure relief housing and a pressure relief valve poppet. The pressure relief housing defines a first pressure relief cavity that is disposed between a first end wall defining a first flow port and a first wall defining a passageway and a second pressure relief cavity disposed between the first wall and a second wall. The pressure relief valve poppet is movably disposed within the first pressure relief cavity and the second pressure relief cavity. The vent valve has a vent housing and a vent valve poppet. The vent housing defines a vent cavity that is disposed between the second wall defining a vent flow port and a second end wall. The vent valve poppet is movably disposed within the vent cavity.

The invention discloses a lifeboat which can be used in a typhoon day. The boat includes a hull. The hull is provided with a helical gear space symmetrically on the lower side of the transmission space. On the left side of the energized magnet, when the hull is stabilized, the motor needs to be automatically loosened and taken up to stabilize the hull. At the same time, the fan blades can be rotated to drive the ship forward or backward by the rotation of the helical gear, which can fully convert the excess electrical energy into The mechanical energy can also slide the rotation axis of the fan blade down to the fixed connection with the first rotating rod. When a person steps on the pedal, the mechanical energy generated can drive the fan blade to rotate to make the boat move forward or backward, and a life buoy is also designed. Insufflation function and push-out lever, which can automatically throw out the inflated life buoy for rescue when rescue is needed.

A liquid-ingress control device, comprising a casing having an interior and an exterior, and optionally a liquid-activated trigger positioned in the casing interior; the casing comprising an exterior liquid entry control surface defined by a perimeter in sealing relationship with an edge of a cap, the cap having an interior cap surface formed to define a cap space between the interior cap surface and the liquid entry control surface; the liquid entry control surface comprising a liquid entry port comprising a tube extending between the exterior and interior of the casing through an aperture formed in the entry control surface, the tube optionally comprising a flange positioned exterior to the casing; the cap comprising at least two flow apertures positioned such that liquid contained within the cap space is capable of egress under gravity from the cap space, independently of the orientation of the device.

A sea anchor includes a textile tube and a resiliently flexible support. The textile tube may include a first end and a second end. The first end may have a rim defining a mouth and the second end may be closed. In various embodiments, the resiliently flexible support is coupled to the first end of the textile tube. The resiliently flexible support, in response to the sea anchor being deployed, may be configured to expand the mouth and retain the mouth open. In various embodiments, the textile tube has a conical shape, with the mouth of the first end being a base of the conical shape and the second end being a point of the conical shape. The resiliently flexible support is a ring coupled to the rim of the first end of the textile tube, according to various embodiments.

An evacuation system (10) includes an electrically insulating inflatable conveyance (11), which is stowed within, and deployed from, a framework (21) attached to an interior structure (45) or exterior structure (43) of an industrial vehicle (38). The inflatable conveyance (11) preferably has a flexible base (12) affixed to, and dependently supported by, longitudinally disposed closed tubular members (15), and may take the form of a chute that may be configured to function as a slide or as a ladder. The chute may be enclosed with a canopy (17), or may be open but provided with upwardly extending side walls (16). In implementations of a canopy (17), transparent egress windows (19) may be provided. Transversely oriented straps (14) form safety steps and/or hand rails in a ladder configuration of the chute.
