摘要： A dispenser selectively mixes one or more chemical fluids into a motive fluid such as water by using diverting motive fluid to one or more channels formed in an eductor body, at least one of the channels being an eductor. When the motive fluid passes through the eductor, a selected chemical fluid is eductively drawn into the venturi of the eductor, producing a mixed fluid having a desired total flow rate and dilution ratio. Additional dilution ratios, flow rates, and chemical fluids are selectable by diverting motive fluid to another channel or combinations of channels. Carry-over of chemical fluid between dispensing is avoided by diverting the motive fluid rather than by diverting the concentrated chemical fluid.

摘要： A fuel nozzle has a modular construction wherein valve, venturi and spout modules are mounted in a bore formed in a nozzle body. The main fuel valve is controlled, independently of fuel pressurization, in response to a mechanical signal input, acting through a servo valve. The mechanical signal input is provide by a finger displaced trigger, acting through a pivotal lever arm and latching means that form part of the automatic shut off means for preventing overfill of a fuel tank. The venturi module has a venturi passage for generating a vacuum employed in the automatic shut off mechanism. The venturi module includes a bypass passage that enables sufficient vacuum force to be generated at both high and low flow rates. The spout module comprise an extruded spout (including a venturi vent passage) and a pair of mechanical adapter shells that are mechanical locked onto the spout and mechanically locked to the nozzle body, to secure the several modules in assembled relation.

摘要： A remote activation dispensing apparatus for dispensing fluids. An actuating device positioned on a dispensing tube is operably connected to a flexible elongated member, which is operably connected to a valve in a dispensing unit. Upon manipulation of the actuating device, the valve is actuated for passing or cutting off fluids from the dispensing unit to the dispensing tube.

摘要： An improved selector valve includes a sealing disc with a sealing face biased against an opposed sealing face of a port plate. The sealing disc has a channel located in the sealing face which communicates with an outlet port and a single selected inlet port on the port plate while simultaneously sealing off all other inlet ports. A venturi eductor has a suction passage sealed directly to the port plate outlet for connecting the venturi directly to a selected inlet port. A connection bridge spans a tolerance gap between the port plate to the eductor. The flow path of the fluid through the selector valve has been streamlined to eliminate stagnation points and minimize turbulent flow of the fluid. As a result, the dilution rate of the chemical and water being dispensed upon actuation of the valve is improved and purging of the selector valve is eliminated because the amount of residual chemical remaining in the selector valve is minimized. Moreover, the material selection of the sealing disc enables a wider temperature range of operation for the selector valve without thermal expansion or contraction which may detrimentally effect the seals between the adjacent proponents of the selector valve.
摘要翻译：一种改进的选择阀包括密封盘，其密封面偏压在端口板的相对的密封面上。密封盘具有位于密封面中的通道，该通道与端口板上的出口和单个选定的入口连通，同时密封所有其它入口。文氏管喷射器具有直接密封到端口板出口的吸入通道，用于将文丘里管直接连接到选定的入口。连接桥跨越端口板与喷射器之间的公差间隙。通过选择阀的流体的流动路径已经流线化，以消除滞留点并使流体的湍流最小化。结果是，由于阀门的致动时分配的化学品和水的稀释率得到改善，并且由于残留在选择阀中的剩余化学物质的量最小化，所以选择阀的清洗被消除。此外，密封盘的材料选择使得选择阀的操作温度范围更宽，而不会发生热膨胀或收缩，这可能不利地影响选择阀的相邻支撑体之间的密封。

摘要： A vacuum assisted, vapor recovery fuel nozzle comprising a nozzle body and a spout mounted thereon. The spout comprises an inner tube and an outer tube. The inner tube and a passage in the body provide a fuel passage. The inner and outer tubes define a vapor return passage in the spout. The inner end of the outer tube is provided with a radial flange, which is clamped, by a breakaway nut, on the nozzle body to mount the spout thereon. The nozzle is provided with an automatic shut off mechanism, which includes a venturi valve for generating a negative pressure. In the absence of an overfill condition, this negative pressure is vented to atmosphere through a vent tube disposed in the vapor return passage. A normally closed vapor return valve, mounted on the nozzle body, is opened in response to the nozzle's flow control valve, so that vapors will be drawn into the entrance of the vapor return passage at the outer end of the spout. The spout is formed by telescoping the inner tube into a ferrule and the ferrule into the outer tube to provide a reenforced outer end for the spout. The nozzle body is compositely formed by a body member, a vapor cap and a housing for a main valve trip mechanism. The coaxial hose is attached to the hand grip of the nozzle at a downward angle. An optional, vestigial shroud is provided to prevent escape of vapors during delivery of fuel.

摘要： A dispenser for dispensing at two flow rates eductively draws a chemical fluid such as a concentrated cleaning solution for diluting with a motive fluid such as water. Using eduction rather than gravity feed provides a consistent dilution ratio over a range of pressures of the motive fluid. A chemical reservoir contains the chemical fluid and a bottle insert assembly for interfacing to the dispenser. The bottle insert assembly seals an opening to the reservoir when the reservoir is not inserted in the dispenser, preventing leaks. Also, the bottle insert assembly includes dual pickup tubes, each with a purge accumulator, to allow dual rate flow at the same or different dilution ratios as well as drawing back unused chemical fluids from the dispenser to avoid carryover or contamination.
