An active drain liquid trap configured for use with a fuel tank system and constructed in accordance to one example of the present disclosure includes a trap body, a float and a pilot. The trap body defines a first inlet, a second inlet and an outlet. The first inlet is fluidly connected to a fuel pump. The second inlet is fluidly connected to a vapor line. The float is rotatably mounted about a float pivot. The pilot moves between an open and closed position. Rotation of the float causes the pilot to be urged into an open position and fluid to be drained from the trap body through the outlet.

It is disclosed a FLVV including: an upper cover provided in the fuel tank, and having an outlet duct; a casing coupled to the upper cover; the float, which is elastically provided inside the casing so as to be movable upward and downward, has a first valve seat provided on the upper surface of one side thereof so as to open and close a first outlet port by principle of a lever, and has a recessed surface formed at one side of the upper surface thereof; the plate elastically provided by a second spring at the recessed surface formed at the float, so as to open and close a second outlet port while moving upward and downward; and a lower cover closing the lower part of the casing and having the float elastically provided by a first spring.

In at least some implementations, an assembly includes a float having a void with an inlet leading into the void in a first direction, and at least one retention surface that is not parallel to the first direction and a hinge received at least partially within the void. The hinge has at least one retention feature that cooperates with the at least one retention feature of the float to inhibit removal of the hinge from the float in a second direction opposite to the first direction, and the hinge is formed from a polymeric material. In at least some implementations, the hinge has a melting point similar to or lower than the melting point of the material of the float, and the hinge is formed separately from and is pressed into the void in the float.

A valve device forming a ventilation flow channel of a fuel tank includes a float valve; an inside case including a valve opening relative to the float valve at an upper portion, and housing the float valve; an outside case receiving the inside case from an upper open end, and provided with a bottom portion; and an attachment portion relative to a tank side. A flow channel which becomes one portion of the ventilation flow channel is formed between a side portion of the inside case and a side portion of the outside case, and a through hole is provided in the side portion of the inside case. Furthermore, an engagement claw relative to the outside case is provided directly above the through hole.

An air vent hole includes a substantially columnar hole main body portion, a first hole portion formed on the upper side of the hole main body portion, and a second hole portion formed on the lower side of the hole main body portion. Each of the first hole portion and the second hole portion partly has, in a cross section of the hole portion substantially orthogonal to a first direction that is a longitudinal direction of the hole main body portion, a cross-sectional area smaller than a cross-sectional area of a cross section of the hole main body portion substantially orthogonal to the first direction. A float inserted into the air vent hole is movable between a position where the float occludes the first hole portion and a position where the float occludes the second hole portion. The float occludes the first hole portion under the weight of the float. However, the float is pushed up by air. Furthermore, the float is formed of a material having a smaller specific gravity than a liquid to be filtered. Thus, the float is pushed up by the liquid to occlude the first hole portion.

The disclosure relates to a tracking device configured to track an object in space, such as the sun, as the object moves across the sky. The tracking device may further be configured to direct a payload toward the object or toward an angle relative to the object. The tracking device may continuously or intermittently determine the location of the moving object, and adjust the position of the payload accordingly. The tracking device may calculate the position of the moving object based on GPS information, such as triangulated coordinates of the tracking device, date, and time. Generally, the tracking device may be capable of tracking an object such as the sun from anywhere on the earth's surface. The tracking device may employ one or more actuation assemblies to position the payload toward or relative to the moving object. The one or more actuation assemblies may operate through linear motion.

A filter assembly includes a vent system. The vent system includes an inner standpipe, a check valve, an outer standpipe and a cover. A sidewall of the check valve extends around the inner standpipe, and an end wall of the check valve is positioned over the inner standpipe. A sidewall of the cover extends around the outer standpipe, and an end wall of the cover is positioned over the outer standpipe.

A filling head for an operating liquid tank, in particular of a motor vehicle, comprising a filling tube with an inlet end, which lies farther away from the tank, and an outlet end, which lies nearer to the tank, the filling tube for conducting operating liquid in a filling direction from the inlet end to the outlet end, a venting arrangement with an inflow end, which lies nearer to the tank and an outflow end which lies farther away from the tank, which end is provided for passing of gas in a counter-flow direction with respect to liquid flowing in the filling direction, in a venting direction extending from the inlet to the outflow end, the venting arrangement is provided, at least in the area of its outflow end, separate from the filling tube, the venting arrangement has a valve with a gas valve body, which is movable between a closed position, in which a gas flow in a valve passage is prevented, and a passage position, in which the gas may flow in the valve passage past the gas valve body, the valve having a liquid valve body, which is movable between a blocking position, in which a liquid flow in the valve passage is blocked, and an open position, in which the valve passage past the liquid valve body is open.

The present invention relates broadly and separately to a flow control valve and a float control valve assembly for use in the refilling of storage vessels, particularly fuel tanks. The invention also relates generally to a vessel overfill protection system. The flow control valve comprises a valve body defining a fluid passageway disposed between a fluid inlet and a fluid outlet and a piston assembly located at least in part within the fluid passageway. The piston assembly includes a piston support to which a piston is slidably mounted for opening and closure of the fluid outlet. The piston support includes at least one fluid sampling passage arranged to provide pressurised fluid from the fluid inlet to an upstream surface of the piston which is urged for opening of the fluid outlet to permit flow of fluid through the fluid passageway. The float control valve assembly includes a float assembly body adapted to mount within a vessel to be filled with fluid via the flow control valve. The float control valve includes a pilot valve and a pilot control passage in fluid communication with the flow control valve. The pilot valve is operatively coupled to a float member for closure of the pilot control passage on flooding of the float housing to promote closure of the flow control valve.
