differential pressure valve
1differential-pressure valve — Inside the Bosch CIS fuel distributor, these valves (there is one for each cylinder) maintain a constant pressure drop at each of the control plunger slits, regardless of changes in the quantity of fuel flow …
2differential pressure — The pressure difference between two systems or volumes. Normally, it refers to cabin pressurization, and the gauge shows the differential pressure in addition to the cabin altitude. Once the differential pressure exceeds a specified figure, the… …
3Valve — This article is about the flow control device. For the game developer, see Valve Corporation. For the electronic component, see Vacuum tube. For other uses, see Valve (disambiguation). These water valves are operated by handles. A valve is a… …
4Pressure measurement — The construction of a bourdon tube gauge, construction elements are made of brass Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure pressure are called pressure gauges or vacuum gauges. A… …
5Pressure — This article is about pressure in the physical sciences. For other uses, see Pressure (disambiguation). Pressure as exerted by particle collisions inside a closed container …
6frequency valve — [1] A valve located in the fuel distributor of some vehicles with a continuous injection system and catalytic converter. This valve continually adjusts the air/fuel ratio to varying engine operating conditions, because it is controlled by a… …
7Lambda valve — In Bosch CIS, a device that regulates pressure in the lower chamber of the differential pressure valve, in response to a signal from the lambda (oxygen) sensor. Also called frequency valve or a timing valve …
8timing valve — In Bosch CIS, a device that regulates pressure in the lower chamber of the differential pressure valve, in response to a signal from the lambda (oxygen) sensor. Also called Lambda valve (Bosch s term) or a frequency valve …
9Pressure vessel — Vertical pressure vessels installed in a structure A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. The pressure differential is dangerous and many fatal… …
10pressure differential switch — A hydraulic pressure operated switch (often included in a combination valve) which activates the brake failure warning light when one of the brake circuits (in a dual circuit system) falls due to a system leak and associated pressure drop …
