20090272440 | FREEZE PROTECTION FOR ON-BOARD VEHICLE EMISSIONS TREATMENT SYSTEM - Freeze protection of an on-board emissions treatment substance storage and distribution system in a vehicle includes moving the emissions treatment substance away from a primary fuel/vapor area after filling of the emissions treatment system. In one embodiment an on-board emissions treatment system has a fill tube with a portion extending into a primary fuel fill tube to facilitate co-fueling of the primary fuel and emissions treatment substance. A pressure differential or vacuum is created in the emissions treatment fill tube after filling to move the emissions treatment substance away from a check valve disposed at the terminal end of the fill tube to prevent freezing of the check valve after filling. The emissions treatment substance may be moved out of the co-located portion of the fill tube to an area where passive or active heating of the fill tube may be applied to further reduce susceptibility to freezing. | 11-05-2009 |

20100313966 | Freeze Resistant Manifold Assembly and System - A freeze resistant manifold includes a plurality of conduits, junction, and expansion device. Each conduit of the plurality of conduits includes a respective first end in fluid communication with a respective second end. The junction is defined by each of the respective first ends of the plurality of conduits in direct fluid communication with a remainder of the first ends of the plurality of conduits. The expansion device includes a housing, plug, and linear actuator. The housing has a first housing end and a second housing end. The first housing end is in fluid communication with the junction. The plug is disposed between the first housing end and the second housing end. The plug has a substantially fluid-tight, sliding engagement with an inner wall of the housing. The linear actuator is to urge the plug towards the first housing end with a predetermined amount of force. The plug is held proximal to the first housing end by the linear actuator in response to a fluid pressure in the junction being less than a predetermined normal working pressure. The plug is moved towards the second end in response to the fluid pressure in the junction exceeding the predetermined normal working pressure. | 12-16-2010 |
20120085427 | Outlet Valve for a Frost-Preventing Faucet - An improved outlet valve for a frost-preventing faucet substantially employs an axial slot defined at a central top inside the inlet passage for being inserted by an elastic element and an axial post. A first stop ring is disposed around the stop valve. The first stop ring and the stop valve are inserted into a limiting slot of a hollow stop sleeve disposed under the stop valve. A second stop ring disposed around the stop sleeve is inserted into a lower section of an inner wall of the inlet passage. A bottom of the second stop ring is disposed above a top of the top porcelain. Cooperating the subject improved configuration with the top porcelain allows the water to be supplied upward since outlet gates of the bottom porcelain and the top porcelain stay abreast without a blockage. When a water pressure is larger than a rebounding force of the elastic element, the stop valve upwardly compresses the elastic element. Thereby, the water travels through the inlet passage disposed at the middle section of the plug and enters into an outlet hole at the top end of the tubular receiving valve seat. The water is further upwardly guided into a supplying pipe of the faucet. When the water pressure is smaller than the rebounding force of the elastic element, the elastic element compresses the stop valve. Thereby, an axial post of the stop valve is downwardly inserted into the limiting slot of the stop sleeve for impeding the water flow, so that the porcelain valve unit is prevented from freezing, and the water pressure is capable of controlling a feeding of the water flow. | 04-12-2012 |

20130284280 | Tubular plastic hydrant - In a hydrant assembly, the combination comprising an outer tubular member having a first flow port.; an inner tubular member having a closure thereon to close the port in relatively axially advanced position of the closure, and to open the port in relatively axially retracted position of the closure that allows fluid flow through the port to an outlet, control means to control relative movement of the inner and outer members. A second port may be located sidewardly of the outer tubular member to pass fluid in relatively retracted position of the closure to relieve fluid pressure in space formed between the inner and outer members, the inner member being elongated and extending lengthwise in the outer tubular member. The outer tubular member may consist of plastic material. Travel of the closure acts to allow expansion of fluid as it freezes, to relieve pressure build-up within the assembly. | 10-31-2013 |
20140034145 | Advanced Valve Actuation System with Integral Freeze Protection - A valve and actuator assembly includes a valve to control a flow of liquid into a coil, and an actuator to control the valve. The assembly includes a first temperature sensor to sense the temperature of liquid flowing through the valve, a second temperature sensor to sense the temperature of air surrounding the coil, and a flow meter to measure a flow rate of liquid through the valve. The actuator includes a module that receives data from the first and second temperature sensors and from the flow meter, and determines, based on data received from the flow meter and temperature sensors, a likelihood that the liquid in the coil will freeze. The actuator operates the valve to allow a minimum flow of the liquid through the valve and coil during a potential freeze condition. The minimum flow is sufficient to prevent the liquid in the coil from freezing. | 02-06-2014 |
20150075638 | PLUMBING FREEZE PROTECTION SYSTEM - A plumbing freeze protection system comprises a fluid connection between a water supply line and a waste line. The fluid connection bypasses a plumbing fixture fluidly connected to the water supply line. A valve operable with the fluid connection alternately prevents water flow from the water supply line to the waste line, and allows water flow from the water supply line to the waste line within about 25 percent of maximum volumetric flow rate of the water supply line through the fluid connection. A timer is adapted to control the valve. The valve is open for a predetermined time period to deliver a short duration, high volumetric flow rate of water to the waste line to minimize ice formation in, and remove existing ice from, the water supply and waste lines. | 03-19-2015 |
