Abstract: The present disclosure is directed to a combination air valve that uses buoyancy to lift seals into place, preventing media from escaping from the valve. Once the seals are in place, pipeline pressure is used to open and close the valve. The combination air valve includes a piston assembly which includes a main disc, a piston head located above the main disc, a float below the main disc, and a float shaft joining the float to the piston. When no media is in the valve the float is at the bottom of the valve and the main disc is down, allowing gases to leave the valve. The float is lifted as media enters the valve, thus using buoyancy to lift the main disc into place, preventing media from escaping from the valve. Once the seals are in place, pipeline pressure is used to open and close the valve.

Abstract: A float or a near neutral buoyancy weight operated liquid pressure control valve includes a body which together with an end cap form a cavity and retain a diaphragm therein. A back-pressure chamber is formed between the end cap and the diaphragm and the diaphragm includes a seal section which seats on an inlet port. The diaphragm seal also separates the inlet from an outlet formed in the body. A float support arm reciprocally operates a valve opening and closing control pin mounted in an associated bleed passage formed longitudinally through a control pin mounting. In an open mode the bleed passage vents the chamber. In a closed mode the pressure in the chamber displaces the diaphragm to close the valve. A slide is coupled to the diaphragm so as to be displaced therewith and prevent excessive pressure to distort the diaphragm once the seal closes on port.

Abstract: A connector attached to a fuel tank for connecting a ventilation flow passage thereof to the fuel tank is provided. The connector includes an upper chamber provided with a first communication portion relative to the ventilation flow passage; and a lower chamber provided with a second communication portion relative to the fuel tank, and a third communication portion relative to the upper chamber. A mortar-shaped portion narrowing toward a lower side is formed in a bottom portion of the upper chamber. The third communication portion is formed in a bottom of the mortar-shaped portion, and recesses and protrusions are formed in a wall face of the mortar-shaped portion.

Abstract: A reservoir tank for a vehicle brake system has a tank body including upper and lower shells joined together along mating surfaces. A float and a fluid level sensor are mounted in a fluid level detecting chamber defined in the tank body. The float is fitted on a shaft of the fluid level sensor. A partition plate is fitted in the lower shell to restrict a flow of hydraulic fluid into and out of the fluid level detecting chamber. The partition plate is disposed near the top end of the shaft of the fluid level sensor to restrict the distance by which the float can move vertically. A filter, the fluid level sensor and the partition plate are all set in the lower shell. The filter and the partition plate having their top ends pressed against the bottom ends of partitioning walls of the upper shell. Thus, the filter and the partition wall are held in position in the tank body between the upper and lower shells. No separate retainer for the float is necessary because the partition plate serves also as a float retainer.
