摘要： The invention relates to a device for controlling the flow and/or pressure of a pressurized gas, and specifically to a tap for a pressurized-gas cylinder. The tap includes a body having a gas inlet, a gas outlet, and a passage connecting the inlet to the outlet. The tap also includes a valve for closing the passage, as well as a pressure indicator downstream from the closing valve. The pressure indicator is translatably operated and includes just two stable positions, i.e. one that corresponds to the presence of pressure, and the other to the absence of pressure.

摘要： A pressure gauge including a hollow cylinder, a first housing member having a first pressure inlet disposed at a first end of the cylinder, and a second housing member having a second pressure inlet disposed at a second end of the cylinder. The pressure gauge also includes a piston slidably disposed in the first housing member. The piston includes a remote indicator coupled to an end of the piston. At least a portion of the remote indicator extends into the hollow cylinder. A spring is disposed in the cylinder abutting the remote indicator and urges the remote indicator toward the second housing member. An increased pressure difference between the first pressure inlet and the second pressure inlet causes the remote indicator to move away from the second housing member and toward the first housing member, and the remote indicator provides a measure of the pressure difference relative to indicia included on the pressure gauge.

摘要： A pressure gauge 20 includes a diaphragm 36 having a first side 64 and a second side 66 and occupying a first state or a second state as a function of a pressure of a fluid 59 in contact with the first side 64. A sensor 68 communicable with the second side 66 of the diaphragm 36 senses the first state or the second state to produce a signal which is processed by a circuit 40 to produce an output. An indicator 42 provides an output representing the first state or the second state of the diaphragm 36 based on the output from the circuit 40.

摘要： A pressure gauge 10 has an indicator needle 23 and a scale plate 22. A preset pressure indicating member 31 extending along a pressure scale in a circular arc pattern is slidably attached to a front wall 11 of a case 13, and provided with a first display section 35. An opaque shield portion 36 provided with a second display section 37 at one end thereof is provided to a transparent cover 26 rotatably attached to the front wall. The transparent cover 26 drives the preset pressure indicating member 31 to set a preset pressure range between the first display section 35 and the second display section 37 which is observable from the outside through the transparent cover 26. Therefore, it is easy to change a preset pressure range which is within a measurable range of the pressure gauge.

摘要： An improved pressure reading structure for a pressure gage is disclosed, comprising a data plate, a rotable pointer and a protection casing. The data plate includes a central area and an extended area next to and connected to the central area, both of the areas being positioned on different planes to serve as an upper area and a lower area thereof respectively. In addition, the rotable pointer has a first end mounted above the central area of the data plate, a second end mounted above the extended area of the data plate, and a needle relative to the data plate to form a space. Accordingly, tire pressure can be read from different view angles, and also, use of the pressure gage becomes more convenient.

摘要： A pressure gauge including an indicating element and a pressure sensing element. The indicating element includes an opaque screen and an indicator dial that are relatively movable, the screen and dial being relatively moved along a path of movement between first and second limits of movement in a progressive manner in response to a variation of pressure sensed by the sensing element. The screen is arranged to mask the dial from view and is provided with a window through which a portion of the dial can be viewed during the relative movement. The dial has two visibly distinct regions on its surface which is visible through the window, the visibly distinct regions being juxtaposed to one another along the path of movement. A first of the regions is in registry with the window when the sensed pressure is at or above a first predetermined pressure, and a second of the regions is in registry with the window when the sensed pressure is at or below a second predetermined pressure which is lower than the first predetermined pressure.
