International Classification:

F16K 24/04

US Classification:

137202, 137 43, 137 6815

Abstract:

A device and method for venting a tank comprising an intermediate shutoff valve as part of a cover that closes a tank opening. The intermediate shutoff valve is placed between an existing valve and a vent port in a liquid storage tank. The shutoff valve is operable to substantially fluidly seal the vent port when the vent valve is displaced greater than a predetermined amount. The intermediate shutoff valve facilitates complete removal of the existing vent valve during an impact wherein a wall of the storage tank impacts the existing valve. Upon impact, the intermediate shutoff valve is operable to close and seal a tank opening created by the displacement and removal of the existing vent valve.

International Classification:

G01F 23/32
G01F 23/00

US Classification:

73317, 73313

Abstract:

A contactless, sealed fuel level sensor for determining a fuel level in a fuel tank and producing a level indicative signal includes a frame, a cover, a float arm, a float and a light-responsive sensor. The frame is configured to have a cavity formed therein. The cover is connected to the frame to enclose the cavity. The float arm is coupled to one of the frame or cover. The float is connected to the float arm and configured such that the float moves the float arm as a level of fuel increases and decreases in the fuel tank. The light-responsive sensor is configured to generate a fuel level signal indicative of a fuel level in the fuel tank based on the movement of the float arm. The fuel level sensor may also include a light source such as a light emitting diode (LED). The light-responsive sensor may be a single photoelectric sensor located in the sealed cavity, or an array of photoelectric sensors located in the sealed cavity. The fuel level sensor may also include a rotatable hub connected to the float arm for movement as the arm moves and where rotation of the hub varies an amount of light impinging on the photoelectric sensor.

US Classification:

137202, 137 43, 403326

Abstract:

A fill limiter vent valve (FLVV) adapted for suspension downward into a fuel tank has upper and lower housing members having openings in their cylindrical walls cooperating to define a spill-over level for fuel into the FLVV producing float-initiated vent valve closure during a fuel fill event. The lower housing member has a latching member fixedly engageable with one or more cooperating latching features of the upper housing member in a plurality of relative axial positions; and the spill-over level is varied by relative axial movement of the housing members between those positions. Axial alignment of the latching member and the cooperating latching features is maintained by axially aligned, interacting surface features of the housing members.
