Abstract:
An injector, including: a moveable armature having a bore and upper and lower control surfaces; a lower housing including a bore and upper and lower stationary control surfaces; and a flow geometry defined along an exterior of the armature. The armature includes a transverse flow path fluidly coupled with the armature bore and the flow geometry. The lower housing includes a transverse flow path fluidly coupled with the lower housing bore. Upon moving the armature from a first position to a second position, a first flow path is formed between the flow geometry and the lower housing transverse flow geometry through a space between the lower stationary control surface and the lower armature control surface, and a second flow path is formed between the armature bore and the lower housing transverse flow geometry through a space between the upper stationary control surface and the armature upper control surface.

Abstract:
Provided is a valve having a movable valve member with an orifice, a plunger movable to block/allow flow through the orifice, and a resilient biasing member for resiliently biasing the valve member away from the valve seat. When the plunger is moved to a position allowing flow, fluid flows through the orifice creating a pressure differential in the valve that in combination with the resilient biasing member moves the valve member to a position allowing flow through a main passageway of the valve. During a low or no flow condition, the valve member is held in the position allowing flow to prevent a drop in performance of a system utilizing the valve that would result if the valve member moved to a blocking position.

Abstract:
The present invention relates to a kit for an LPG fuel for petrol run engines and in particular, a kit of electronic and hydraulic components for the realization of a dual fuelling LPG/petrol system (100) particularly suitable for outboard engines of boats navigating in waters with high salt content. Said kit includes a tube-bundle heat exchanger (10) and a pressure regulator (20) separated one from the other and made of antioxidant materials and devices. The heat exchanger (10) is provided at its end with two respective sacrificial anodes (12b, 11b) for the protection from corrosive galvanic currents and with one temperature sensor (11c) placed at one of said ends. The kit also includes a plurality of electrohydraulic LPG injectors (I) and an electronic control unit (CE) set to manage and adjust the operation of such injectors (I), of the pressure regulator (20) and of a plurality of other devices. Said kit also includes an electronic commutator (SW) set for a bilateral electrical connection with the electronic control unit (CE) and includes a switch for the commutation from one feeding mode (LPG) to another feeding mode (petrol) and vice versa.
Abstract:
Exemplary embodiments of a gas biased pressure regulator comprise a capsule subassembly and a regulator body. The regulator body is adapted to connect to a source of pressurized gas. The capsule subassembly is removably received within the regulator body and includes a capsule body and a piston. The piston is axially slidable between fluid release and fluid seal configurations. When the piston is in its fluid release configuration, an output chamber is placed in fluid communication with the source. When the piston is in its fluid seal configuration, the output chamber is sealed from fluid communication with the source. A pressurizable bias chamber within the capsule body contains a bias pressure urging the piston toward its fluid release configuration. Pressure from the source urges the piston toward its fluid seal configuration. The piston may also have a fluid charge configuration for facilitating the pressurization of the bias chamber.
Abstract:
The object of the present invention is a methane pressure reducer/regulator for feeding internal combustion engines which comprises a body divided into three chambers, communicating with each other by means of high resistance conduits and by means of an opening/closing element which is integral with an elastic diaphragm, whose surface is proportionally larger than the opening/closing element so that a modest pressure in the chamber upstream from the elastic diaphragm is sufficient to bend it, overcoming both the methane pressure resistance in the adjacent chamber, and the methane pressure resistance in the chamber directly connected to the tank(s), as well as the counter spring resistance. When the elastic diaphragm bends, it pushes a stem whose end is integral with the opening/closing element that allows or prevents the methane passage through a hole connecting the chamber from which methane is sent to the engine to the chamber wherein methane comes directly from the tank(s). Further, a conduit connects the chamber where a sufficient pressure is reached to bend the diaphragm, to the chamber from which low pressure methane is sent to the feeding system of the engine; according to a configuration, said conduit is provided with an on-off valve and a throat, or, alternatively, only with the on-off valve. The pressure regulator/reducer is completed by a pressure sensor, a pressure control valve, valves and connections to electronics which controls the engine feeding operation.
