Abstract: A separating device for separating particles from fluid in which an inlet passage is defined in the body member of the device for receiving the fluid and an outlet passage extends parallel to the inlet passage for discharging the fluid. A chamber is connected to the inlet passage for receiving the fluid from the inlet passage, and a separator is disposed in the chamber for separating particles from the fluid as the fluid flows through the chamber. A cover is connected to the chamber and the outlet passage for receiving the separated fluid, reversing the direction of the separated fluid and directing the separated fluid to the outlet passage for discharge from the body member. The cover can be a filter unit for providing additional filtering of the fluid.

Abstract: A fluid meter is disclosed which comprises a body having a crankcase portion and two axially-aligned cylinder portions. The first and second cylinder portions each have an inner end in fluid communication with the crankcase portion, and respective first and second head ends opposing the inner ends. A crankshaft is rotatably mounted in the crankcase portion and includes two crank pins radially offset from the crankshaft and angularly spaced sixty degrees apart. Pistons are reciprocally mounted in the cylinder portions and are drivingly connected to the crank pins so that rotation of the crankshaft is effected by reciprocation of the pistons within the cylinders. First, second, and third ports are provided having fluid communication with the respective first head end, the second head end, and the crankcase portion. A rotary valve is provided having inlet and outlet ports arranged to sequentially register with the first, second, and third ports when the crankshaft is rotated.

Abstract: A service station dispenser for gasoline with a vapor collection system is disclosed which processes the electrical signal typically produced by the fuel meter which represents the volume flow rate of fuel to the tank to control the displacement volume of an electrically driven vacuum pump so that a simple vacuum intake disposed preferably inside, but not sealed with, the filter neck can be used to collect only the vapors displaced from the fuel tank by the fuel. The vacuum pump is preferably controlled by the same digital processor which calculates and displays volume and cost to the customer, and a single vacuum pump can be used in connection with single point of sale, multiple fuel grade systems or with multiple point of sale, single grade systems for enhanced economy of cost.
