Abstract: A reservoir assembly for retaining a fluid includes a body having a base and external side walls defining a cavity. A baffle has a top surface spanning the cavity and includes a peripheral wall substantially conforming to the external side walls and extending to the base. A lid is connected to the body. The cavity is divided into a first, second and third compartment by a cooperation between the top surface of the baffle, a plurality of walls of the baffle, the base of the body and the external side walls of the body. The first and second compartments are in fluid communication with each other through the third compartment. An inlet port and an outlet port for allowing fluid to enter and exit the cavity are fluidly connected to the body and are fluidly connected to each other by the first compartment to direct a flow of the fluid.

Abstract: Arranged in a fuel tank of a motor vehicle are guide elements and guide plates which deflect a flow of the fuel toward a wall of the fuel tank at a flat angle. Splashing noises of the fuel are thereby markedly reduced. The guide plates form a channel with a calming region, in which the flow of the fuel is throttled.

Abstract: A fuel tank includes an inlet port communicating with a fuel decelerating section of the tank in which the inflowing fuel is decelerated. The decelerated fuel is delivered to a fuel intake compartment of the tank which contains a filter. The filtered fuel is then delivered to a fuel storage area of the tank which includes a hose leading to an outlet port. A buoyant member is mounted on the inlet end of the hose to enable that inlet end to rise to or near the surface of fuel in the tank. Sediment drains are provided in the bottom of the tank for removing sediment from the fuel intake compartment and the fuel storage area.

Abstract: An internal valve and metered positive displacement pump for a pressure fluid tank. The tank defines a fluid compartment, and first and second vessels are positioned within the protective envelope of the tank. A bellows pump assembly disposed in the first vessel includes a bellows and a piston cylinder arrangement positioned within and attached to the bellows. Pressurized fluid is pumped into and out of the first vessel to actuate the piston cylinder arrangement. With this actuating movement fluid is pumped from the compartment through a valve in the second vessel and into the second vessel for removal therefrom. The valve is normally closed against the working pressure of the fluid in the compartment by a spring bellows relief assembly in the second vessel. The force of the fluid pump by the piston cylinder arrangement opens the valve, and a check valve prevents fluid from flowing back from the valve into the first vessel.

Abstract: An automotive fuel system including a reservoir having upper and lower chambers on opposite sides of a partition in the reservoir, a high pressure fuel pump having an inlet connected to the lower chamber, a low pressure fuel overage return pipe returning overage fuel directly to the lower chamber, and a low pressure pump transferring fuel from the tank directly to the upper chamber. A drain in the partition conducts gravity induced fuel flow from the upper chamber to the lower chamber at a rate equal to the difference between the rate at which the high pressure pump withdraws fuel from the lower chamber and the rate at which overage is returned to the lower chamber through the overage return pipe.

Abstract: A method and apparatus for head control of irrigation waters in above-ground gated pipe located on a gradient. The method includes the steps of: measuring the elevation drop over the length of said pipe; providing an in-line container at predetermined elevation drops along said pipe, said container having an inlet for receiving water from the upstream portion of said pipe and an outlet for discharging water to the downstream portion of said pipe; dividing each of said containers with a height adjustable partisan located between said intake and said outtake; and adjusting the height of each of said height adjustable partisan to provide the desired flow from the openings in the pipe upstream of said partisan being adjusted.

Abstract: In order to facilitate temporary storing of oil in an underwater receptacle, for instance the pontoon of a semi-submersible vessel, the receptacle is subdivided by bulkheads into a series of tanks. A first tank is connected to a production unit by way of a conduit, or by way of a branch pipe to a delivery conduit. The tank located remotely with respect to the conduit communicates with the surrounding sea by an opening. The bulkheads are provided with upper and lower openings, respectively, and a screened passage extends between these openings. When oil is supplied to the first tank static or pump pressure will expel water through opening, and oil will fill the tanks in due order in the direction away from the first tank. When oil is withdrawn, water from the surrounding sea will flow in through opening and further on through the tanks towards the first tank.

Abstract: A pressurized liquid conduit is broken or interrupted to provide an upstream inlet into a downstream outlet from a visual monitoring device. The device, which includes a collection chamber surrounding the conduit outlet and a transparent tube extending upwardly therefrom surrounding the upstream inlet is sealed in air tight relation around the liquid line on either side of the interruption. An air lock or bubble, greater in volume than the volume of the transparent tube, is contained in the chamber/tube assembly to maintain a constant pressure on the liquid collected in the chamber causing a controlled flow of liquid through the downstream side of the line. A baffle in the collection chamber disperses air bubbles, which might tend to form in the collected liquid, prior to the time the air bubbles reach the outlet in the chamber.

Abstract: A reservoir for hydraulic fluids and hydrocarbon fluids having an outer tank, an inner tank contained therein, an inlet conduit for the delivery of fluids to the outer tank with a minimum of turbulence, an outlet for withdrawal of fluids from the inner tank, and a vent for venting air into and out of the outer tank.

Abstract: The invention involves positioning the working end of a vertical pump below the surface elevation of the fluid, enclosing a space around the pump with a structure extending below the surface and having a submerged opening to the main reservoir, and drawing a vacuum in the enclosed space in order to raise the surface elevation in the enclosed chamber in order to maintain a minimum working depth for the vertical pump that will prevent air entrainment by vortexing during periods of low fluid levels outside the chamber.

Abstract: A simplified, energy efficient, low cost liquid flow controlling weir apparatus is provided for "in tank" flow equalization and surge control. The apparatus is especially adapted for use in waste water treatment plants at tank outlets, and includes first and second, opposed, spaced apart upright weirs; the inboard first weir adjacent tank water is of lesser height than that of the outboard weir, and the latter is provided with one or more apertures therethrough at a level below the upper margin of the first weir. When water within the tank rises past and overflows the inboard weir plate, liquid flow is controlled by the outboard weir plate openings, water is rapidly backed up in the tank as storage, and tank discharge is maintained at a relatively uniform rate until the tank storage capacity is reached. The outboard weir plate prevents tank overflow, and is advantageously set at a height for overflow at 125-135 percent of design flow through the system.

Abstract: A hydraulic liquid reservoir includes a tank that has a plurality of walls and a baffle structure which divides the inside of the tank into three compartments. An inlet is connected to one lower compartment while an outlet is connected to the second lower compartment and a third upper compartment is interconnected with both the first and second lower compartments at a location below the liquid level in the tank. The baffle structure is designed such that there are high points in each the first and second compartments which are in communication with the inside of the tank above the liquid level in the third compartment to vent any air from the first and second compartments into the top of the tank within the third compartment.
