A combination washing and drying appliance includes a tub positioned within an outer cabinet. A rotating drum includes a perforated wall. The rotating drum is rotationally operable within the tub. A blower delivers process air through an airflow path that includes a processing space within the rotating drum and an interstitial space defined between the tub and the rotating drum. An operable vent is selectively operable between a venting position and a closed position. The operable vent defines a passive flow of ambient air between the processing space and an area outside of the tub. The operable vent is operable to the closed position during a spin function of the rotating drum.

An exhaust valve for inflatable diving equipment includes a valve body having an annular peripheral flange providing a sealing stable connection with a band of material along the edge of a passage opening in the delimiting wall of a hollow body, and a cylindrical collar surrounded by the annular flange and provided with coupling members to corresponding coupling members of a cover cap of the valve body. The cylindrical collar internally defines an annular valve seat that surrounds an opening communicating with the hollow body and that cooperates with a shutter provided on the side of the valve seat opposite to the internal space of the hollow body and stably stressed, in the closed position, against the valve seat, by an elastic element interposed between a wall of the cover cap and the facing side of the shutter. Optional displacement organs move the shutter from the stable closed position of the valve to an open position. The cover cap covers the valve seat and the shutter toward the outside and has a passage opening coupled with an interception and/or a deflection screen of particles or other suspended material, leaving free or openable a discharge passage.

A fluid control apparatus includes a piezoelectric pump and valve. The valve includes a second valve housing, second seal member, diaphragm, first seal member, and first valve housing and has a structure in which they are laminated in sequence. The first valve housing includes a second vent and third vent, has a valve seat, and includes six cavities. The second valve housing has a first vent and first vent and includes a valve seat and six first protrusions. The second valve housing further includes six second protrusions nearer the outer edges than the six first protrusions, as seen in the x-axis direction in plan view.

A combined paddle and pump can be used to propel a small boat. The handle telescopes with a locking nut that may be loosened to allow extension and retraction of the handle. The handle is hollow throughout and a pair of check valves are provided. One check valve opens when the handle is extended and the other opens when the handle is retracted. When one check valve is open, the other is closed. When the distal end of the paddle is placed within a volume of water or exposed to atmospheric, extension and retraction of the handle results in a fluid first being sucked into the hollow interior of the handle and then propelled out of the handle. A seal assembly prevents debris from binding tubes of the handle.

A flexible pipe having one way fluidic flow valves containing a working fluid that generates one way fluid flow to power a generator. Preferably the pipe is buoyant or otherwise flexed by motion of any supporting or surrounding liquid, so that waves in the liquid flex the pipe. Preferably an added interior pumping arm is provided to increase the fluid flow from flexing.
