| Number | Title | Issue Date |
| 7114379 | Fuel meter for outboard engines An apparatus and method for determining a parameter related to fuel consumption in an engine are disclosed. An electrical sensor senses an electrical control signal used to control fuel introduced into the engine, such as by controlling a valve or fuel injector of t... | 10/03/2006 |
| 7008400 | Diaphragm pump and pump for double-breast pumping A motorized pump is disclosed that includes a flexible diaphragm fitting within a rigid member, a motor drive mechanism for drawing a puller member attached to the diaphragm away from the rigid member to create a space between the diaphragm and the rigid member and ... | 03/07/2006 |
| 5811676 | Multiple fluid meter assembly A fluid meter assembly in which a housing is provided that has two enclosures formed therein. At least one cylinder is formed in each enclosure and receives a piston. Fluid is admitted into each cylinder to drive its piston and pass the fluid through a co... | 09/22/1998 |
| 5686663 | Fluid meter utilizing two connecting rods for connecting two pistons A fluid meter in which a crankcase and two axially-aligned cylinders are defined in a housing. A crankshaft is disposed in the crankcase and two pistons are respectively mounted in the cylinders for reciprocal movement. Two connecting rods respectively co... | 11/11/1997 |
| 5648606 | Fluid meter having a crankshaft with two angularly spaced crank pins radially offset from the crankshaft 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 a... | 07/15/1997 |
| 5440925 | Flow calibrator The invention relates to a high accuracy flowmeter for testing and calibrating flowmeters and the like, and more particularly to a positive displacement flowmeter which may include a cylinder (12), a piston (10) within the cylinder (12) which makes a clea... | 08/15/1995 |
| 5094106 | Liquid meter for fuel pumps A liquid meter for fuel pumps is so designed that the liquid enters through the bottom of the meter and is measured as it passes upwardly through the meter housing and is discharged at the top, which shortens the path the liquid must follow in passing thr... | 03/10/1992 |
| 4938054 | Ultrasonic linear meter sensor for positive displacement meter A positive displacement meter for measuring the volume of liquid dispensed over a given period of time includes at least one pair of pistons moving in counter opposition to one another within a pair of cylinders, an acoustical transducer located through a... | 07/03/1990 |
| 4781066 | Linear sensing apparatus for positive displacement meter Linear sensing apparatus for a positive displacement meter includes relative to each piston of the meter, an elongated rectangular member rigidly attached at one end to the top face of its associated piston, and carrying at its other end a multiwindowed m... | 11/01/1988 |
| 4583400 | Flow meter A flow meter including a housing having inlet and outlet ports, at least two associated pistons provided respectively in respective cylinders in the housing, metering chambers defined respectively on one sides of respective pistons, passages formed in the... | 04/22/1986 |
| 4561304 | Positive displacement piston flowmeter A positive displacement radial piston flowmeter includes pistons coupled to one another by connecting rods. Fluid passageways interconnect the cylinders and inlet and outlet ports formed in the housing. Piston movement is sensed by a pair of linear differ... | 12/31/1985 |
| 4450720 | Flowmeter connecting rod assembly A flowmeter connecting rod assembly for use with a positive displacement radial piston flowmeter. The flowmeter includes pistons mounted radially about the central axis of an indicator shaft. The indicator shaft has an eccentric crank pin extending from i... | 05/29/1984 |
| 4250748 | Fuel volume meter Two pairs of reciprocating pistons are selectively driven by a volume of fluid to be measured. The pairs are perpendicular to one another and connected to a crank for converting the reciprocating motion into rotary motion to magnetically drive a recording... | 02/17/1981 |
