A float assembly for a multifunction fuel vapor vent valve with a float having a recess formed in the upper surface of the float with a slot formed in the side of the float and communicating with the recess. A raised surface portion is formed in the bottom of the recess and downwardly extending projections are formed in the slot at the recess. A flexible wafer like valve disk is inserted in the slot and deformed or curled to pass under the projections and over the raised surface and into the recess. When fully received in the recess the disk returns to its flat configuration; and, the downward projections prevent removal without distortion. Radially inwardly projections about the recess retain the disk for limited lost motion in the direction of float movement.

A drinking fluid dispenser (24) includes a bottle (4) positioned on a dispenser base (20). Mounted inside the bottle (4) is a valve (10) closely connected to the float (12) via an actuator arm (14). The valve (10) is located above the fluid (52) of the bottle (4) and is connected to a continuous flow fluid source. During normal operation, when the liquid level (50) of the fluid (52) rises and falls in the bottle (4), the float (12) floating on the fluid (52) by buoyancy closes and opens the valve respectively. The dispenser also has a pressure tube (18) with a hole through said bottle (4) above the fluid (52) of said bottle, thereby maintaining atmospheric pressure inside the bottle (4).

The invention provides a motor vehicle internal combustion engine speed-sensitive linear automatic supercharging air supply device. The air supply device is provided with a supercharging chamber communicating with an air inlet pipe of an internal combustion engine. An air inlet of the supercharging chamber faces against the wind generated by a motor vehicle during advancing, and the air pressure in the supercharging chamber and the air supply amount of the internal combustion engine are automatically increased and reduced along with change of the vehicle speed. The supercharging chamber can beof a combined structure, or an eggshell type structure, a whistle type structure, or a horn type structure or a straight pipe type structure. The combined supercharging chamber is composed of a supercharging chamber body and an auxiliary supercharging chamber body on the upper portion. A valve grid is arranged between the supercharging chamber body and the auxiliary supercharging chamber body. Anair pressure valve is arranged on the valve grid and is limited between guide rods to float up and down. The upper end of the auxiliary supercharging chamber body is provided with an auxiliary air inlet used for being sealed when the air pressure valve floats up. An internal combustion engine air inlet pipe communicates with the auxiliary supercharging chamber body. A pipe serves as the air inletand goes into the supercharging chamber body in the tangential direction. Air is fed into the internal combustion engine through the wind pressure generated by the motor vehicle during running to increase the air supply amount and promote sufficient burning of fuel oil. The power of the internal combustion engine is increased. Oil consumption is reduced. Carbon deposit of the internal combustionengine is reduced. The purchase cost and the maintenance cost of the motor vehicle are reduced.

The invention provides a high and low water level adjusting rotary guide valve floating ball valve. The floating ball valve comprises a floating ball, a support rod, a bracket, a four-way reversing valve and a floating ball main valve, wherein the support rod passes through a center shaft of the floating ball; the floating ball can slide upwards and downwards along the support rod; the upper segment of the support rod is connected with one end of an upper pull rod and one end of a lower pull rod through hinge pins; the other end of the upper pull rod is connected with a balance block; the middle segment of the upper pull rod can rotate about a fixed shaft on the bracket; the other end of the lower pull rod is connected with a valve of the four-way reversing valve; three holes are formed in the four-way reversing valve, and are connected with the lower control cavity, the water inlet and the upper control cavity of the floating ball main valve in sequence; the fourth hole is an emptying hole. The high and low water level adjusting rotary guide valve floating ball valve has the beneficial effects that the frequent starting of the floating valve main valve is avoided, and the service life of the floating ball main valve is prolonged; when the inlet water pressure is excessively low, the opening and closing of the floating valve main valve can be controlled normally, and automatic control is realized.
