Compressed Natural Gas Vehicle Safety System and Method
20200171945 · 2020-06-04 ·

A multiply-redundant system that prevents a driver from starting and/or moving a vehicle if a compressed natural gas fill system is not correctly and completely disconnected from the vehicle. One or more sensors in combination with one or more optional microswitches combine to lock-out the vehicle's ignition or otherwise prevent it from starting and/or moving. For different levels of safety, different combinations of sensors can be used with the lowest level having a single proximity sensor sensing the presence or absence of a high-pressure fill hose. The highest level of safety being achieved by having separate proximity sensors on the fuel fill hose fitting, the gas cap cover and a manual safety valve along with a redundant microswitch. An optional override that may be restricted as to the number of times it can be used can allow starting with a faulty sensor in order to allow maintenance.

Depressurizer

CRYOGENIC STORAGE VESSEL

A cryogenic storage vessel having an inner vessel defining a cryogen space; an outer vessel spaced apart from and surrounding the inner vessel, defining a thermally insulating space between the inner vessel and the outer vessel; and a receptacle defining passages for delivery of liquefied gas from the cryogen space to outside the cryogenic storage vessel. The receptacle has an elongated outer sleeve defining an interior space in fluid communication with the thermally insulating space that is sealed from the cryogen space; an elongated inner sleeve extending into the interior space defined by the elongated outer sleeve defining an inner receptacle space that is fluidly isolated from the thermally insulating space; and a collar extending around an inner surface of the elongated inner sleeve which seals against a cooperating surface of a pump assembly when a pump assembly is installed in the cryogenic storage vessel thereby dividing a warm end from a cold end of the receptacle. A motor for driving the pump can be installed within the cryogenic storage vessel.
