The pilot port fluidly communicates with a control/warning device such that, when a secondary ride height is reached by the vehicle, the pilot port signals the control/warning device in order to maintain the vehicle at the secondary ride height. The pilot port alternatively provides an air pressure boost in order to quickly re-inflate the air springs of the vehicle to return the vehicle to the primary design ride height. | 08-06-2009 |
| 20090250128 | PROPORTIONAL SELECTOR VALVE FOR SELECTING BETWEEN TWO PRESSURE SOURCES - A selector valve selects between the supply of a primary pressure supply and a secondary pressure supply to a downstream use. The selector valve moves between a first position at which it supplies fluid from a primary line to the use, and a second position at which it supplies fluid only from a secondary line to the use. The selector valves moves through an intermediate position at which fluid is supplied from both supplies to the use. | 10-08-2009 |

| 20130263951 | GAS BYPASS DEVICE - A bypass device used in conjunction with a gas meter has a normal mode and a bypass mode. In the normal mode, the bypass device routes gas through the gas meter to a customer. In the bypass mode, the bypass device routes gas through a bypass path so that the gas meter can be serviced or replaced without interrupting gas service to the customer. Manual operating ball valves select either the normal mode or the bypass mode. Each ball valve includes a rotatable diverter ball with a 90° flow passage. Each diverter ball is mounted within the bypass device between pair of polymer annular valve seats. | 10-10-2013 |
| 20140026994 | FLUID SENSING AND DISTRIBUTING APPARATUS - A fluid sensing and distributing apparatus having a distribution plate and an indexing plate is provided. The distribution plate may include a first distribution face and a second distribution face and a plurality of ports extending between the first distribution face and the second distribution face. The first distribution face may further contain a plurality of arc grooves. The indexing plate may have a first indexing face, a first group of ports in fluid communication with the distribution plate arc grooves, a second group of ports in fluid communication with the distribution plate ports, and a first group of ports in fluid communication with a second group of ports. The apparatus has a means for driving rotational movement between the indexing and distribution plates. The apparatus may further contain a plurality of ports on the distribution plate in direct fluid contact with an external apparatus matching plurality of ports. | 01-30-2014 |
| 20140083540 | AUTONOMOUS VALVE ASSEMBLY FOR THE REGULATION, DEPRESSURIZATION AND PRESSURIZATION OF PNEUMATIC EQUIPMENT - An autonomous valve assembly for the regulation, depressurization and elevation of the pressure in pneumatic equipment that presents a valve body | 03-27-2014 |
| 20140196806 | FLOW DIVERTER AND OPERATION OF SAME - A diverter assembly for a shower tub includes a housing having an inlet for receiving fluid and first and second outlets for discharging fluid. An endless advancement structure includes a flow plate fixed to the housing and a gearing arrangement rotatable relative to the flow plate. The flow plate includes a first opening in fluid communication with the first outlet and a second opening in fluid communication with the second outlet. The gearing arrangement includes third openings in fluid communication with the inlet. A handle is coupled to the gearing arrangement for selectively rotating the gearing arrangement in a single direction relative to the flow plate to alternate between placing the gearing arrangement in a first condition aligning one of the third openings with the first opening and placing the gearing arrangement in a second condition aligning one of the third openings with the second opening. | 07-17-2014 |
| 20140261810 | Run Selection Mechanism - A run selection mechanism is provided for selectively directing the flow of particulate material from an air cart.
