A damped compressor used in mobile appliances. The appliances may comprise a compressor which is disposed within a housing and is in fluid communication with a refrigerant system. Within the housing there is an improved damping or stabilizer system which limits movement of electric or mechanical portions, or both, of the compressor within the housing. At startup and shutdown, when oscillations of the components within the housing are generally maximized, the components are limited from contacting the housing internal structure so as to inhibit damage to the compressor and reduce the noise associated with such contact. The components are also damped from movement associated with the mobile application of the compressor.

Present embodiments provide a roof fan assembly with numerous improvements. The roof fan assembly includes a cover which allows for a fan shroud to be opened. The structure includes a base clamp which connects to the roof of an RV. The base clamp includes a fan and motor which push or pull air out from the RV or into the RV. The base clamp includes a worm gear assembly which includes a worm gear structure to open and close the shroud. The arm may include a sleeve which moves relative to the arm and connects to the shroud at the opposite end. The base clamp includes mounts for connecting the base clamp to the roof as well as allowing for connection of the cover to the fan assembly as a whole. Still further, the structure provides integrated hinges in the base clamp to allow connection of the shroud to the base clamp for pivotal movement.

A low-noise, high-volume air mover is used in a recreational vehicle to push air. The air mover is smaller than previous designs used, moves more cubic feet of air than previous designs used, and produces less sound than previous designs used.

An air vent may cover an opening formed in a structure to block water or debris from entering an interior of the structure through the opening. The air vent is movable between a closed and an open position to selectively block or allow fluid communication between the interior and an exterior of the structure.

Vent housing

A vent cover for covering an opening in a building structure to vent its interior is provided. The vent cover includes a hollow cover member with an open bottom for positioning over and covering the opening in the building and a front end with an opening. A grill is removably secured in the opening in the front end of the cover member. The grill has a plurality of partitions. Each of the partitions is defined by intersecting members, which have a tapered cross section for accelerating the flow of air through the grill. The grill also has a splash guard and an overhang structure optimal for preventing rain, snow and water from entering the grill and the opening in the building structure. The cover member may be aerodynamically shaped for use atop vehicles such as trailers and RVs.
