A home-based, low-cost, self-contained, fast-fill natural gas refueling station for providing compress natural gas (CNG) fuel for motor vehicles. The station compresses utility supplied natural gas and stores the CNG in a CNG storage facility located inside the station. In preferred embodiments the refueling station is located adjacent to a driveway at a home. The compressor preferably is a multi-stage gas compressor having at least three stages of compression. Applicant estimates that savings based today prices for CNG as compared to gasoline, a typical family with only one car could pay for the station in three years. If the family has several cars the station could pay for itself much earlier.

According to one embodiment, a CNG dispenser is provided that includes a user-actuatable button for allowing selection of a pressure to which to fill a vehicle tank with CNG, and a controller for opening a high pressure fill valve to dispense high pressure CNG into the vehicle tank while monitoring the pressure of the vehicle tank until the pressure reaches the user-selected pressure. According to another embodiment, the controller is operable in a selected one of two modes of operation. The two modes of operation include a one-pressure bank operation mode in which only the input of a high pressure fill valve is coupled to a CNG supply line, and a three-pressure bank operation mode in which the inputs of each of three fill valves are coupled to respective CNG supply lines. A graphic fuel gage may be provided on the dispenser payment terminal screen.

Tap for pressurised fluid, with or without integrated pressure regulator, including a body housing a fluid circuit having an upstream end to be connected to a pressurised fluid reservoir and a downstream end to be connected to a user device, the circuit including a valve for controlling the flow rate in the circuit, the valve being controlled by a lever pivotally mounted on the body of the tap between a first state rest position and a second state active position wherein, the outer surface of the tap comprises a groove and in that, in its first position, a first portion of the lever is housed in the groove and does not protrude or protrudes slightly with respect to the outer surface of the tap, while a second portion or the lever protrudes outside the groove.

A hydrogen filling apparatus that can quickly fill vehicles equipped with multiple large-capacity fuel tanks with hydrogen gas while complying with filling protocol. The hydrogen filling apparatus (100) of the present invention includes: a plurality of filling systems; a filling control device (10, 20) for each of the filling systems; a filling pipe communicating with a rear facility in each of the filling systems; a set of filling members (for example, flow control valves, flow meters) interposed in each of the filling pipes and connected to each of the filling control devices; and a filling hose connected to each of the filling pipes, each filling hose having a filling nozzle at a tip; wherein one of the plurality of filling control devices has a function of selectively exerting a first control mode that controls only the filling system including the filling control device and a second control mode shared as a control device for the plurality of filling systems, and a switching means for switching between the first control mode and the second control mode in the one of the filling control devices is provided.

A device for regulating the pressure of a compressed gas, comprising a body with a gas inlet, a gas outlet and a gas passage fluidly interconnecting the inlet and outlet; a mobile element carrying a shutter cooperating with a seat in the gas passage, the shutter and the seat forming a regulating valve; a hand-wheel operatively linked to a spindle rotatably mounted on the body; wherein the spindle is hollow and houses a spigot with a cam, the spigot being linked in rotation with the spindle and cooperating with a counter-cam spigot movable in translation but not in rotation relative to the body, and acting on the mobile element or on a shut-off valve for selectively shutting-off and opening the gas passage.

To provide a filling apparatus capable of suppressing radial movement of a rod-shaped member (connecting pin) of a nozzle, and preventing damages and deformations (recesses and so on) from generating on an outer peripheral surface of the connecting pin. A filling apparatus (100) according to the present invention includes: a storage tank for storing hydrogen fuel; a filling nozzle (10) for filling a hydrogen gas from the storage tank through a fuel filling system to an in-vehicle hydrogen filling tank mounted on a vehicle; a rod-shaped member (2: connecting pin) and a main body portion (1) mounted on the filling nozzle (10); a sealing member (3: laminated sealing member) arranged on (a radially outer peripheral portion of the rod-shaped member of) the main body portion (1); a guide member (4: pressing member), projecting radially inward, mounted on a portion separated from an end side of the rod-shaped member (2) (from a receptacle 20 side in an in-vehicle hydrogen filling tank to the fuel filling system); and means for protecting an outer peripheral surface of the rod-shaped member (2) from slide on the guide member (4).
