摘要： A diaphragm type fluid pressure gauge comprises a case formed of an injection molded thermoplastic. The bottom wall of the case selectively defines a rear axial fluid connection or a radial fluid connection to a fluid chamber defined within the case. The fluid chamber is closed by a diaphragm which is clamped against an annular radial surface in the case by a thermoplastic ring which is melt-welded to the case. The other face of the ring provides a mounting for a movement mechanism for driving a pointer in response to axial displacement of the diaphragm.

摘要： An apparatus and method for recording the compression pressure of internal combustion engines, wherein a pair of recording elements, such as a stylus and a recording sheet, are movable relative to each other by a pressure sensitive element, and the compression pressure acts upon one of the recording elements to first move the recording element from a position of rest, after which the two recording elements are brought into contact with each other, and the pressure is then relieved from the one recording element, resulting in a line being drawn while the recording element returns to its position of rest.

摘要： Pressurized fluid circuits are provided which are suitable for use in a pressure drop detector for a pressurized fluid fire alarm system. The pressurized fluid circuits are provided as channels in the surface of a block of material and include one channel connected to a source of fluid pressure. The channels are associated with valve regions by means of which, with a diaphragm pressed thereagainst, a required one or more of the channels can be closed off.In its application to a pressure drop detector a normally pressurized region of the diaphragm may support a mechanical linkage of the detector such that if the pressure drops, on release of pressure in the system, the collapsing of the diaphragm allows the mechanical linkage to be released thus actuating a fire alarm.

摘要： The present invention relates to a static air pressure diffuser that is adapted to be secured to an external probe extending from a structure for use in sensing and measuring static air pressure about the diffuser. Structurally, the static air pressure diffuser of the present invention comprises two generally circular flat plates secured together in spaced apart relationship with the lower plate being provided with a generally centrally located opening formed therein that is communicatively connected with the external probe when the static air pressure diffuser is properly mounted atop the probe. Between the two plates is defined an open area that is radially open to air currents from all directions therearound and which acts to channel air horizontally through the open space between the plates such that a true static air pressure reading may be taken about the opening formed in the lower plate between the two plates and wherein dynamic air pressure factors are minimized due to the horizontal flow of air currents perpendicular to the opening within the lower plate.

摘要： Device for visual indication of a maximum fluid pressure condition reached during a given interval of time. Useful for the in-flight recording of fluid pressure condition e.g., in the reduction gear box of a jet engine where excessive pressures are indicative of incipient failures, the device comprises a body having a cavity in fluid pressure communication with system fluid, an indicator movable relative to the body cavity in response to changes in system fluid pressure, and locking means limiting indicator travel to a single direction indicative of a relatively higher pressure condition in the system.

摘要： An automatic tire inflator assembly includes an input hose that is fluidly attachable to an air source to receive compressed air from the air source. An output hose is fluidly attachable to an air stem of an inflatable tire. A control unit is fluidly coupled to the input hose to receive the compressed air from the air source. Additionally, the control unit is fluidly coupled to the output hose to inflate the inflatable tire. A gauge is fluidly coupled to the control unit and the gauge is settable to determine the pre-determined threshold pressure. The control unit is turned off when the gauge measures air pressure that exceeds the pre-determined threshold pressure to inflate the inflatable tire to a desired air pressure.
