Aerodynamic suction ventilator

A device, comprising:

• a first hollow body defining a first surface;
• a second hollow body defining a second surface, at least one aperture being formed in the second surface, the second hollow body and the first hollow body being spaced apart from one another with the first surface facing the second surface;
• and
• at least one hollow member extending between the first body and the second body, the at least one hollow member placing the at least one aperture in fluid communication with the first hollow body;
• wherein a distance between the first surface and the second surface decreases in a direction approaching the at least one aperture.

A device, comprising:

• a first base body defining a first internal space;
• a second raised body defining a second internal space and including at least one aperture, the second raised body and the first base body being spaced apart from one another;
• and
• at least one hollow member extending from the first base body to the second raised body, the at least one hollow member placing the at least one aperture in fluid communication with the first base body;
• wherein a space defined between the first base body and the second raised body forms a venturi such that a low pressure is formed at the at least one aperture when airflow passes between the first base body and the second raised body.

A surface mountable device comprising:

• a hollowed base body for being mounted on a surface;
• a hollowed raised body being supported and secured on said base body with at least one hollowed elongated member, wherein a free space is defined between said base body and said raised body;
• and
• at least one opening being provided on a surface of said raised body facing said base body, and being channeled to the internal space of said base body through the internal spaces of said raised body and said at least one hollowed elongated member;
• wherein said free space being generally narrower at the at least one opening than along a surrounding perimeter and forming a first contracting and then expanding airflow path for any approaching wind direction to thereby create a low pressure or a suction effect at said at least one opening and communicate said suction effect to any space connected to said internal space of said base body.

A roof vent for use with a roof, comprising:

• a lower body including a top surface;
• an upper body supported above the lower body, the upper body including a bottom surface and an opening in the bottom surface;
• and
• at least one hollow member providing fluid communication between an interior of the upper body and an interior of the lower body;
• wherein the top surface of the lower body and the bottom surface of the upper body face each other and define a space therebetween;
• and
• wherein a distance between the top surface of the lower body and the bottom surface of the upper body decreases from a periphery of at least one of the lower body and the upper body to the opening.

A roof vent for use with a roof, comprising:

• an upper body including a bottom surface;
• and
• a lower body including an interior and a top surface opposite the bottom surface of the upper body;
• wherein at least one of the top surface of the lower body and the bottom surface of the upper body includes a convex shape so that a portion of said at least one of said top and bottom surfaces curves toward the other of said top and bottom surfaces defining a space therebetween;
• wherein the bottom surface of the upper body defines at least one opening;
• wherein the interior of the lower body is in fluid communication with the opening defined by the upper body;
• wherein said space is configured to allow air to pass between the top surface of the lower body and the bottom surface of the upper body, thereby reducing air pressure at the opening defined by the upper body;
• and
• wherein the top surface of the lower body lacks any opening that provides flow directly from the interior of the lower body to the space.

An arrangement associated with a roof, comprising:

• a roof component;
• and
• a roof vent comprising
• an upper body including a bottom surface defining at least one opening, and
• a lower body including a top surface;
• wherein the top surface of the lower body and the bottom surface of the upper body face each other and define a space therebetween;
• wherein a distance between the bottom surface of the upper body and the top surface of the lower body decreases in a direction approaching the opening defined by the bottom surface of the upper body;
• wherein the opening defined by the bottom surface of the upper body of the roof vent is in fluid communication with an underside of the roof component;
• and
• wherein the top surface of the lower body lacks any opening that provides flow directly from an interior of the lower body to the space.

A roof vent for use with a roof, comprising:

• an upper body including a bottom surface;
• and
• a lower body including an interior and a top surface opposite the bottom surface of the upper body;
• wherein at least one of the top surface of the lower body and the bottom surface of the upper body includes a convex shape so that a portion of said at least one of said top and bottom surfaces curves toward the other of said top and bottom surfaces defining a space therebetween;
• wherein the bottom surface of the upper body defines at least one opening;
• wherein the interior of the lower body is in fluid communication with the opening defined by the upper body;
• wherein said space is configured to allow air to pass between the top surface of the lower body and the bottom surface of the upper body, thereby reducing air pressure at the opening defined by the upper body;
• and
• wherein the roof vent defines a flow path extending from the interior of the lower body to the opening defined by the upper body, wherein the flow path provides the fluid communication of the interior of the lower body with the opening defined by the upper body, and wherein the flow path does not include said space.

An arrangement associated with a roof, comprising:

• a roof component;
• and
• a roof vent comprising
• an upper body including a bottom surface defining at least one opening,
• a lower body including a top surface;
• wherein the top surface of the lower body and the bottom surface of the upper body face each other and define a space therebetween;
• wherein a distance between the bottom surface of the upper body and the top surface of the lower body decreases in a direction approaching the opening defined by the bottom surface of the upper body;
• wherein the opening defined by the bottom surface of the upper body of the roof vent is in fluid communication with an underside of the roof component;
