Abstract: A gaseous fuel mixer assembly for an engine includes a mixer housing forming gas delivery openings, and positioned to extend across a flow path formed by an intake conduit for the engine. A spool valve is within a central bore in the mixer housing and includes gas distribution openings selectively connectable to the gas delivery openings by moving the spool valve within the mixer housing using a piezoelectric actuator coupled with the spool valve by way of a pivot arm. Sealing lands of the spool valve are in an alternating arrangement with the gas distribution openings, such that at the closed position the sealing lands block the gas distribution openings from the gas delivery openings, and at the open position the respective openings are fluidly connected.

Abstract: A method for distributing water from a trap primer to at least one trap. The method includes providing a trap primer having an upper chamber separated by a flexible diaphragm from a lower chamber, and having a resilient gas enclosure located in the lower chamber. Water is provided to the trap primer at a line pressure charging the upper and lower chambers. As a result of a reduction in line pressure, the diaphragm is disengaged from a valve stem opening an orifice and causing the flow of water from the lower chamber to at least one trap.

Abstract: An embodiment providing one or more improvements includes a trap primer with upper and lower chambers separated by a flexible diaphragm which also interacts with a valve stem to start and stop the flow of water from the trap primer to the trap(s). The lower chamber contains a polymeric foam medium such as a foam ring containing closed cells containing gas or gases. In use, equilibration of water pressures in the upper and lower chambers causes distortion of the foam ring, resulting in equilibration of the gas pressure in the closed cells with that of the chambers. A decrease in line water pressure causes water from the lower chamber to be emitted into the traps.

Abstract: A control system for a vehicle having a dry dual clutch transmission (DCT) includes a launch condition detection module, a vehicle stop module, and a vehicle launch module. The launch condition detection module detects a launch condition based on whether (i) the vehicle is on an uphill grade and (ii) a driver of the vehicle has requested power via an accelerator. The vehicle stop module stops the vehicle when the launch condition is detected by (i) commanding an on-coming clutch of the dry DCT to a predetermined position and (ii) applying brakes of the vehicle. The vehicle launch module launches the vehicle after the vehicle is stopped by (i) fully engaging the on-coming clutch of the dry DCT and (ii) opening a throttle to a desired position corresponding to the power request.

Abstract: A regulator valve is structured such that hydraulic pressure to be output from a regulated pressure output port is regulated according to urging forces, i.e., line pressure to be regulated, throttle pressure, spring force from a compression coil spring, and operating force from a plunger, which are applied to a valve spool. The plunger has a small diameter portion and a large diameter portion having a diameter larger than the diameter of the small diameter portion, both of which are axially displaceably retained in a spring receiving sleeve. The small diameter portion is urged in one axial direction at one end of the plunger that protrudes into a spring chamber and faces the valve spool, while the large diameter portion is urged in the other axial direction by range pressure at the other end of the plunger which is isolated from the small diameter portion located in the spring chamber.

The metering face includes a flow force compensating annular void disposed adjacent to the outer diameter that is defined by a lead angle ? measured between the outer surface and a line intersecting the outer surface and tangential to the annular void.

Abstract: The disclosure relates to a method for commissioning pneumatically operated actuators that are controlled by a positioner. To determine the drive type, a constant flow of pneumatic fluid is applied to the actuator during commissioning while a drive-specific characteristic curve of the fed back position is recorded over time. Then the measured characteristic curve is compared with a given specimen characteristic curve. The drive type is inferred from the level of difference or agreement between the drive-specific characteristic curve and the specimen characteristic curve.

The diaphragm is in fluid communication with a transducer for receiving a fluid causing the diaphragm to expand or contract and thereby displacing the spool. The flexible shaft is radially elastic in order to minimize axial backlash between the diaphragm and the spool. The flexible shaft configuration minimizes the spool stroke.

Abstract: Embodiments of the presently described technology provide a direction control valve including first and second orifices and a pressure release mechanism. The first and second orifices provide a path of fluid flow through the valve from an inlet port to a first outlet port. The pressure release mechanism is configured to reduce pressure in the valve through a second outlet port. Embodiments of the presently described technology also provide a direction control valve including first and second fluid communication paths. The first fluid communication path is defined by an inlet port, first and second orifices, and a first outlet port. The second fluid communication path is defined by the inlet port, the first orifice, a pressure release mechanism, and a second outlet port. The second fluid communication path of the valve does not exist until an internal pressure of the valve exceeds a predetermined threshold.

Abstract: A sprayer assembly adapted for releasable attachment to a water supply line, such as for a conventional toilet, is provided. The sprayer includes a three-way valve housing connected to the water supply line for the toilet, the valve housing including a supply conduit and a diverting conduit. A plunger is slidably disposed within the diverting conduit and is biased to a closed position by a biasing means extending between the supply conduit and the plunger. An attachment member is releasably engageable with the diverting conduit and operates to slide the plunger with respect to the diverting conduit in order to allow fluid flow through both the supply conduit and the diverting conduit. The attachment member is secured to one end of a hose that is attached to a sprayer head opposite the attachment member that enables an individual to manually dispense water flowing from the valve housing and through the attachment member and hose to the sprayer head.

Abstract: A flow divider, particularly for use in uniformly dividing a single incoming stream of liquid fertilizer into multiple outlet streams. The flow divider features a housing having a bore therein; a distribution sleeve which fits within the bore; and a distribution needle which slides within the distribution sleeve to evenly divide the incoming flow. Flow enters a distribution chamber formed between a tip portion of the distribution needle and the distribution sleeve, preferably flowing over a series of circumferential ribs located on the tip portion, and accelerates through a narrowing, flow-accelerating region between the distribution needle and the distribution sleeve. The flow is then discharged through a series of orifices in the distribution sleeve and out through a series of flow passageways radially arranged around the flow divider.

Abstract: A hydraulic system for a vehicle including a distributor, or switch, valve for actuating at least two operational areas and supplying the two areas with sufficient amounts of hydraulic medium is provided. The distributor, or switch, valve preferably comprises a flow regulator valve and a solenoid valve, which function so that the supply of hydraulic medium to the steering system always has priority, ensuring that the vehicle is steerable in any situation. When the steering system is operational, the supply of hydraulic medium to other operational areas, such as the clutch and transmission systems, is completely blocked by operation of the switch valve. If, however, the clutch and transmission systems should require hydraulic medium during operation of the steering system, the switch valve allows a small portion of hydraulic medium to be supplied to the clutch and transmission as well.
