| 20090289207 | Airflow regulating valve assembly - The valve assembly disposed within a water supply line upstream of a water meter. The valve assembly is structured to reduce or significantly eliminate the passage of air, separate from water flow, through the meter and includes a housing having an interior channel and a valve body movably disposed within the channel. The valve body includes a sealing structure which is biased, under a predetermined force, into sealing relation with an inlet of the interior channel. The predetermined force is sufficient to prevent displacement of the sealing structure out of the sealing relation with the inlet, but insufficient to prevent displacement of the sealing structure when force from a normal water flow is exerted thereon from within the water supply line. As a result any air flow within the water supply line will be compressed or otherwise disbursed and prevented from passing, independently, through the meter, thereby preventing unnecessary charges being made to the metered facility. | 11-26-2009 |

| 20160084416 | BREAKAWAY COUPLING - A breakaway coupling with system-tight end flanges on the first and second coupling halves is provided.

| 20160160826 | HIGH PRESSURE FUEL SUPPLY PUMP WITH ELECTROMAGNETIC SUCTION VALVE - To reduce collision noise created by the operation of an electromagnetic suction valve provided on a high pressure fuel supply pump. In the present invention, in order to achieve the above object, the mass of a member which collides by magnetic attractive force is reduced to reduce the noise to be generated. The thus configured present invention provides the following advantageous effects. The noise generated when a core and an anchor collide with each other by magnetic attractive force depends on the magnitude of the kinetic energy of a moving element. The kinetic energy to be consumed in the collision is only the kinetic energy of the anchor. The kinetic energy of a rod, being absorbed by a spring, does not contribute to the noise; thus, the energy when the anchor and the core collide with each other can be reduced, whereby the noise to be created can be reduced. | 06-09-2016 |

The coupling assembly includes a biasing element that is to be deflected to provide a seat load to the fluid flow control member when the fluid flow control member is in sealing engagement with a valve seat of the fluid valve and electric power to the electric actuator is removed. | 05-19-2011 |
| 20120298894 | ACTUATING DRIVE FOR SAFETY VALVES HAVING A HIGH ACTUATING TORQUE - An actuating drive for safety valves has a high actuating torque. The actuating drive can be driven by a motor by means of a gear train. When the safety valve is opened, the motor simultaneously preloads a mechanical energy store that is connected to the input shaft of the safety valve and that can be locked. After the lock has been released, the mechanical energy store outputs the stored energy and closes the safety valve in the process. The output of the motor is connected to a planetary gear train, the output rotor of which is connected to the input shaft of the safety valve. The mechanical energy store consists of a number of leg springs that corresponds to the number of planet gears. The leg springs are connected at one end to one of the planet gears and at the opposite end to the housing of the actuating drive in a rotationally fixed manner. | 11-29-2012 |
