摘要： A throttle body includes a secondary passageway having an inlet communicating with a central passageway upstream of a throttle plate disposed in the central passageway. An outlet communicates with an intake manifold of the engine downstream of the throttle plate to allow fluid flow to bypass the throttle plate. A pocket is formed in the throttle body and a seat is formed at the bottom of the pocket to communicate with the secondary passageway. A motor is disposed within the pocket and secured to the throttle body and cooperates with the seat for metering predetermined amounts of fluid flow past the seat. An opening is formed intersecting with the pocket and the outlet to form an internal flow path within the throttle body to allow fluid flow past the seat to flow through the outlet and bypass the throttle plate when in the closed position.

摘要： A rod seal for establishing a seal between an elongate rod and a housing wall around an enlarged opening in the wall through which the rod projects provides a close fitting sliding seal between the rod and the seal to accommodate longitudinal reciprocation of the rod relative to the seal and housing and also provides a sliding seal between the seal and housing wall to accommodate lateral movement of the rod relative to the housing. The sleeve is of a two piece construction which is assembled by a snap fit after the rod has been inserted into one element of the seal so that an enlarged end of the rod may be passed through an opening in the one seal element and the subsequent assembly of the second element achieves a close sliding fit with the unenlarged diameter section of the rod.

摘要： A metering valve, simultaneously controlling a plurality of flow paths with a single poppet movable into and out of engagement with a valve seat in a duty cycle operation has the sealing surfaces of the poppet and seat formed with an accurately flat surface finish to minimize leakage when the valve is closed. The seat surface is formed with recessed areas to reduce the area of contact with the poppet surface to reduce pull-off force while maintaining adequate contact area to dissipate the closing impact forces which are further minimized by controlling the flow of fluid from between the opposed surfaces during valve closure.

摘要： A valve employed in applications where the valve is rapidly cyclically opened and closed over extended periods of time is constructed in a manner such that the impact between a rapidly moving metal valve head and metal valve seat at valve closure is minimized to reduce noise and wear. The valve head engaging element of the valve seat may take the form of a frusto conical belleville washer located with its concave side resting on a flat planar wall surface in the valve housing or a flat washer bridging a frusto conical wall surface in the housing. Fluid filling the recess between the opposed surfaces of the washer and housing wall is expressed from the recess as the frusto conical washer is axially compressed against the wall by the closing valve head to further cushion or damp the resiliently resisted compression of the washer.

摘要： An onboard refueling vapor recovery system for a motor vehicle prevents fuel vapor displaced from the vehicle fuel tank during a refueling operation from being discharged into the atmosphere and stores the fuel vapor for subsequent combustion in the vehicle engine. The system operates in parallel with a known vapor recovery system employed to minimize venting of vapor from the fuel tank through the normal fuel tank vent, this known system being inadequate to cope with the massive surge of vapor expelled during refueling which presently is vented to atmosphere through the fuel tank fill pipe. The refueling vapor recovery system includes a refueling vapor storage canister which is directly connected via a substantially unrestricted flow passage to the head space of the tank when, and only when, a standard fuel dispensing nozzle is operatively located in the fill pipe inlet. The nozzle is inserted through a seal which prevents the escape of vapor from the fill pipe. A float valve in the tank closes the passage to the refueling canister when the tank is filled and the consequent pressure increase will normally actuate the conventional nozzle shutoff mechanism. Emergency devices in the system will sound an audible signal if the nozzle shutoff malfunctions and will dump fuel from the filler pipe if manual shutoff of the nozzle does not occur in response to the audible signal. The system includes further internal pressure and flow regulating devices.
摘要翻译：用于机动车辆的车载加油蒸汽回收系统防止在加油操作期间从车辆燃料箱排出的燃料蒸汽排放到大气中并将燃料蒸汽存储在车辆发动机中用于随后的燃烧。该系统与已知的蒸气回收系统并行操作，用于最小化通过正常燃料箱排气口从燃料箱排出蒸汽，该已知系统不足以应付目前排放到大气中的加油期间排出的大量蒸汽浪涌通过燃油箱填充管。加油蒸汽回收系统包括一个加油蒸汽储存罐，当且仅当标准燃料分配喷嘴可操作地位于填充管入口时，该加油蒸汽储存罐通过基本上无限制的流动通道直接连接到罐的顶部空间。喷嘴通过密封件插入，防止蒸汽从填充管中逸出。当罐被填充时，罐中的浮阀关闭到加油罐的通道，并且随之而来的压力增加将通常致动常规的喷嘴关闭机构。如果喷嘴关闭故障，系统中的紧急设备将发出声音信号，如果喷嘴的手动关闭不响应可听见的信号，则会从加油管中倾倒燃油。该系统包括进一步的内部压力和流量调节装置。

摘要： An EDM circuit that detects power transistor switch failure. A comparator 62 and a sample and hold stage 60 are used during a window of time formed by the off-time of a pulse generator to determine whether power switch MOSFET 30 is conducting. If MOSFET 30 is conducting during the off-time of the pulse generator LED 72 will emit light to indicate a failed power transistor switch.
