摘要： A gas flow safety valve assembly having a main housing of generally solid rigid construction with a main interior chamber divided into an upper compartment and a flow through compartment by a primary diaphragm. Further, the main housing includes an inlet passage leading into the flow through compartment and an outlet passage leading out of the flow through compartment. Upon a gas flow pressure within the flow through compartment dropping below a predetermined minimum acceptable gas flow rate, the primary diaphragm is downwardly displaced resulting in the engagement of a primary displacement member connected thereto with a lever element pivotally positioned within the main housing. The lever element which has a contact plate that engages a magnetic element disposed in the main housing is movable between a shut off orientation and a flow through orientation, the shut off orientation resulting in a blockage of gas flow through the outlet passage until the assembly is reset and the lever element is held in its flow through orientation by a lever biasing element that is sufficiently strong to maintain the lever element in its flow through orientation unless it is affirmatively urged into its shut off orientation, such as by the primary lever misplacement member.

摘要： A power generating assembly structured to have dual functionality by combining an interactive operation of both an engine assembly and a compressor assembly in an at least partially segregated or isolated relation to one another within a common housing. The engine assembly may be connected to anyone of a plurality of different power take-offs in order that the power generated thereby is capable of doing work. Concurrently the compressor assembly is operative to pressurize a fluid flow passing there through and more specifically to increase the pressure of a refrigerant vapor which, after compression is transfer to a condenser or other utilitarian device for operation of a space conditioning or like facility. Interaction between the engine assembly and the compressor assembly is primarily attributable to the workings of a piston assembly comprising at least one but preferably a plurality of free moving pistons, wherein cyclical operation of the piston assembly defines a sequence of alternate compression and expansion phases of both the engine assembly and the compressor assembly.

摘要： A gas flow and pressure regulation and control station to be connected directly between a distribution line of an urban gas distribution network and a user service line, the station including an inlet connector to be connected directly to the distribution line, an outlet level connector disposed in fluid flow communication with the inlet connector and having an axial flow through passage wherethrough controlled levels of gas pass, and an intermediary connection having a flow regulator member which pivotally moves between a normal flow stopping orientation that prevents gas from passing from the outlet level connector to the intermediary connection, and a flow passage orientation, pivotal movement occurring if the pressure of gas flowing through the outlet level connector and contacting a stopper end of the flow regulator member is sufficient because predetermined gas flow and pressure levels which are to be maintained in the intermediary connection have sufficiently dropped such that a regulator diaphragm, which is connected by a pivot rod to a lever end of the flow regulator member, is allowed to move, thereby allowing the flow regulator member to pivotally move allowing gas into the intermediary connection until the predetermined tolerable flow and pressure levels, as set through regulating movement of the regulator diaphragm, is reattained for passage to a user service line through a delivery connector.
