摘要： In a post-mix beverage dispenser in which the concentrate is metered (or portioned) by a positive displacement metering pump having check valves, the improvement of a pressure control device for pressurizing the outlet line from the pump to prevent "blow-thru" of pressurized concentrate through the check valves of the pump, whereby the dispenser can be inexpensively used with a pressurized concentrate source. In addition, a post-mix beverage dispensing system including such metering pump and pressure control device and also including a pressurized canister holding pliable 5+1 juice concentrate at a temperature below 32.degree. F., and a heater for heating the concentrate in the concentrate line.

摘要： A binary syrup system for beverage dispensing including a pair of syrup containers holding different syrup components, a metering device with two inlets connected one to each container and a single syrup outlet connected to a dispenser. The metering device includes a flow channel therethrough for each component, a diaphragm device for equalizing the pressure in each channel, and a metering orifice downstream from the diaphragm device. This pressure equalization in combination with the metering orifices provides the necessary flow control and a constant predetermined volumetric ratio of the two syrup components when mixed to form the complete syrup.

摘要： A post-mix beverage dispensing valve for dispensing syrup and soda in the desired ratio without the need for flow controls for periodic adjustment of the ratio. The valve includes a flow meter for measuring the flow rate of the soda and a pump for dispensing metered quantities of syrup. The pump preferably includes a chamber within a ceramic sleeve having first and second distal ends and a double-acting ceramic piston mounted for reciprocating sliding movement within the sleeve. A solenoid valve control system including a pair of solenoid valves controls syrup flow through the pump, in response to signals from the flow meter. The valve preferably also includes a syrup flow regulator. The valve can include a single externally manually adjustable flow rate control to vary the dispensing flow rate to any desired value.
摘要翻译： 一种用于以期望的比例分配糖浆和苏打的后混合饮料分配阀，而不需要用于周期性调节比例的流量控制。 该阀包括用于测量苏打流量的流量计和用于分配计量的糖浆的泵。 泵优选地包括在具有第一和第二远端的陶瓷套筒内的腔室，以及安装成用于套筒内的往复滑动运动的双作用陶瓷活塞。 响应于来自流量计的信号，包括一对电磁阀的电磁阀控制系统控制通过泵的糖浆流。 阀优选还包括糖浆流量调节器。 阀可以包括单个外部可手动调节的流量控制，以将分配流量改变为任何期望值。

摘要： A refrigeration system for a chilled-product vending machine including a refrigeration compressor, a temperature sensor for detecting the temperature within said vending machine and turning the compressor ON and OFF to define a compressor cycle in response to the detection of predetermined temperature limits, an evaporator coil and evaporator fan means for blowing air across said evaporator coil and circulating said air throughout the vending machine. The system further includes a temperature-based responsive control circuitry including a product sensor for detecting the temperature of the chilled products and cycling said evaporator fan ON in response to detected product temperatures above a predetermined limit, the predetermined limit being less than the temperature required to torn the compressor ON, and a coil sensor for detecting the temperature below a predetermined limit, maintaining said evaporator fan ON during and beyond the end of the compressor cycle, and cycling the evaporator fan OFF when the temperature of the coil stabilizes above the freezing point of water.
