Abstract: A refrigerant muffler includes a plurality of outer walls forming an outer surface of the refrigerant muffler and enclosing a hollow interior thereof with each of the respective outer walls forming a pair with an oppositely arranged one of the outer walls at opposing sides of the hollow interior. An inlet port is provided in a first one of the respective outer walls through which a refrigerant is introduced into the hollow interior of the refrigerant muffler. An outlet port is provided in a second one of the respective outer walls through which the refrigerant exits the hollow interior of the refrigerant muffler. The refrigerant muffler does not include a cross-section therethrough where the outer surface of the refrigerant muffler has a circular shape including both of the outer walls forming one of the pairs of the oppositely arranged outer walls.

Abstract: A flow control device for conveying a fluid therethrough includes a port having an engaging end configured for engagement with a tube fitting and an inner surface defining a passageway configured to provide fluid communication through the flow control device. A shoulder is formed on the inner surface of the port adjacent the engaging end. The shoulder defines a first seating surface and a second seating surface. A protuberance is formed on one of the first seating surface and the second seating surface.

Abstract: In one aspect of the present invention, a hydrocarbon trapping device is provided, including a conduit and an adsorbing element positioned within the conduit. The conduit includes a wall having a wall thickness and the adsorbing element has an adsorbing element thickness that is generally equal to or less than the wall thickness. Furthermore, the adsorbing element defines a leading edge, a trailing edge, and a flow path extending between the leading and trailing edges in a direction substantially parallel to a longitudinal axis of the conduit.

Abstract: A blow molding machine having a tool head that is quickly and efficiently interchanged to minimize the time required to switch between products being blow molded. The tool head is changed without the need for removing the heater bands and with minimal need for alignment during installation.
