摘要： A liquid dispensing and vapor recovery system and a vapor control unit used therein in which the control unit has a pair of inlets for receiving liquid, such as gasoline, from an underground storage tank and for receiving gasoline vapors from a vehicle tank during dispensing of the gasoline into the latter tank. A first passage is provided in the control unit for passing the gasoline from the storage tank to a hose connected to the vehicle tank, and an additional passage is provided in the control unit for diverting a portion of the gasoline. A valve is provided which controls the flow of gasoline through the additional passage in response to the flow of gasoline through the first passage and an injector nozzle is provided in the additional passage for drawing vapors from the vehicle tank and into the second passage for mixing with the gasoline before being discharged back to the storage tank.

摘要： A control apparatus for a water supply system having a motor operated pump for pumping water through a delivery line to one or more valved outlets. The control apparatus includes a pressure switch responsive to the pressure in the delivery line and operable at preselected upper and lower pressure limits to respectively stop and start the pump motor; a main flow control valve which regulates flow from the pump to the delivery line and having a pressure responsive operator; a pressure regulating pilot valve responsive to the pressure at the outlet of the main flow control valve for controlling the pressure on the pressure responsive operator of the main flow control valve to actuate the latter and maintain the pressure in the delivery line substantially constant at a value intermediate the upper and lower pressure limits during normal flow from the delivery line, a pneumatic pressure tank communicating with the outlet of the main flow control valve, and a bypass for passing a restricted flow to the pressure tank and delivery line when the main valve is closed to build up the pressure in the tank and delivery line to the upper pressure limit at which the pressure switch stops the pump motor.

摘要： A water to air heat pump employing an energy and condensate conservation system in which a heat exchange fluid is circulated between two heat exchangers with one normally operating as a condenser and the other normally operating as an evaporator. The condensate from the air passing over the evaporator coil is collected and is passed to the condenser for circulating over the condenser coil. The heat pump is adapted to operate in a reverse mode in which the functions of the heat exchangers are reversed and in which the circulation of the collected condensate to the condenser is terminated.
