  • Patent number: 11059368
    Abstract: A fill limit vent valve for a fuel system includes a housing assembly, an outlet port and a flow dam. The housing assembly has a main housing including a cylindrical body and an upper housing portion. The upper housing portion has a lower wall that defines an orifice and an outer cylindrical wall that defines an upper housing chamber. The outlet port is formed on the main housing and fluidly communicates fuel vapor out of the fill limit valve. The orifice is offset from a centerpoint of the lower wall in a direction away from the outlet port. The flow dam extends from the lower wall into the upper housing chamber and connects on opposite ends to the outer cylindrical wall. The flow dam and upper housing chamber cooperating to form a liquid trap that mitigates the possibility of liquid fuel from reaching the outlet port from the orifice.

  • Patent number: 11054129
    Abstract: A pressure regulator assembly has a normal mode and a regulated fast-fill mode and includes a spring cage and a body coupled together. The spring cage and body define an inlet in fluid communication with an outlet as well as an interior between the inlet and the outlet. A diaphragm assembly mounts in the interior for selectively closing a flowpath between the inlet and the outlet. A preload spring in the interior applies force on the diaphragm assembly so that in the normal mode, the flowpath is closed if a downstream pressure is above a first pressure. An actuation assembly includes a lever coupled to the spring cage and a push rod mounted so that in the regulated fast-fill mode, the lever slides so that the push rod further compresses the preload spring to open the flowpath and regulate flow therethrough if the downstream pressure is below a second pressure.

  • Patent number: 10993412
    Abstract: A pressure regulator for controlling flow of a fluid therethrough is provided. An upper housing member and a primary diaphragm define an upper chamber and a lower housing member and the primary diaphragm define a lower chamber. The pressure regulator further includes: a valve assembly provided within the upper chamber for controlling the flow of the fluid from an inlet body into the upper chamber; a secondary diaphragm provided within the lower chamber and defining a secondary diaphragm driving chamber; and a passageway connecting the inlet body and the secondary diaphragm driving chamber. During operation, the secondary diaphragm driving chamber is filled with the fluid at the inlet pressure, thereby subjecting the secondary diaphragm to the inlet pressure and generating the force for actuating the valve's disengagement from the inlet body. The pressure regulator functions to maintain the outlet pressure at a value that is a predetermined fraction of the inlet pressure.
