摘要： A valve unit for controlling the delivery of a combustible gas through a gas path comprises a first valve seat in the gas path and a first closure means associated with the seat, a first actuator means for the control of the closure means for opening and closing of the valve seat and also motor means for the operating control of the first actuator means. The unit further comprises a second electromagnetic actuator means interposed between the closure means and the first actuator means to urge the closure means so as to close the valve seat, independently of the operating position of the first actuator means, when a predetermined condition occurs which requires the interception of the valve seat.

摘要： There is described a device for reducing the delivery pressure of a combustible gas, particularly for systems supplying gas to internal combustion engines for automotive vehicles, comprising a valve seat (5) positioned in a gas flow tube (2) formed in the body (1a) of the reducer, between an inlet section (3) and an outlet section (4), a diaphragm-operated plug element (6) associated with said valve seat (5) and movable along a predetermined axial direction (X) for the purpose of opening and closing the seat (5), a spring device (9) acting on the to diaphragm to subject the latter to a predetermined resilient load, an actuator rod (11) connected for operation to the plug (6) and to the diaphragm, a pressure compensator element (12) which is fixed to the plug (6) upstream of the valve seat with respect to the direction of flow, and which is axially extensible along that direction as a result of the movement of said plug (6) relative to the valve seat (5). The compensator element (12) comprises a tubular body shaped in the form of a bellows, internally hollow and extending axially between opposite axial ends, one of which is connected to the plug (6) while the other is connected to a stationary structure of the reducer, the inner cavity (13) of the tubular body being sealed to separate it from the outside of the body, a predetermined pressure being created in the cavity (13).

摘要： The pilot burner described comprises a duct defining a gas-mixing chamber, a head mounted removably on the duct at a first end thereof and bearing at least one flame jet, and a gas-supply nozzle mounted in the duct for admitting gas to the chamber. The burner is of the type with a nozzle which is accessible through the first end of the duct after the head has been removed from the end, and the nozzle is fixed in a nozzle-holder which in turn is fixed removably in the duct by insertion in the duct through the first end.
