pressure stroke -
51back pressure — noun 1. : residual pressure on the exhaust side of a steam engine piston against which the steam on the intake side must work 2. : opposition to flow of a liquid or gas due to friction, inertia, gravity, or other cause * * * back pressure noun… …
52mean effective pressure: (MEP) — The average pressure of the burning fuel on the power stroke subtracted by the average pressure on the other three strokes. Pressure is in pounds per square inch. Average pressure on a surface when a changing pressure condition exists. Also see… …
53four-stroke cycle — The sequence of operations by which a reciprocating engine converts heat energy into mechanical energy. During the induction strokes, the fuel air mixture is inducted into the engine. During the compression stroke, the mixture is compressed. The… …
54Hydrocephalus, normal pressure (NPH) — Hydrocephalus is an abnormal buildup of cerebrospinal fluid (CSF) in the brain. The fluid (the CSF) is often under increased pressure which can compress and damage the brain. Normal pressure hydrocephalus (NPH) is a specific form of hydrocephalus …
55Normal pressure hydrocephalus (NPH) — Hydrocephalus is an abnormal buildup of cerebrospinal fluid (CSF) in the brain. The fluid (the CSF) is often under increased pressure which can compress and damage the brain. Normal pressure hydrocephalus (NPH) is a specific form of hydrocephalus …
56NPH (normal pressure hydrocephalus) — Hydrocephalus is an abnormal buildup of cerebrospinal fluid (CSF) in the brain. The fluid (the CSF) is often under increased pressure which can compress and damage the brain. Normal pressure hydrocephalus (NPH) is a specific form of hydrocephalus …
57brake mean effective pressure — A measure of mean effective pressure in a cylinder of a reciprocating engine. It is the average in excess of ambient pressure inside the cylinder during the power stroke. It is measured in pounds per square inch (psi), kilopascals (kPa), or bars… …
58Hair stroke — Hair Hair (h[^a]r), n. [OE. her, heer, h[ae]r, AS. h[=ae]r; akin to OFries. h[=e]r, D. & G. haar, OHG. & Icel. h[=a]r, Dan. haar, Sw. h[*a]r; cf. Lith. kasa.] 1. The collection or mass of filaments growing from the skin of an animal, and forming… …
59Gluhareff Pressure Jet — The Gluhareff Pressure Jet (or tip jet) is a type of jet engine that, like a Pulse jet, has no moving parts. It was invented by Eugene Gluhareff, a Russian engineer who envisaged it as a power plant for personal helicopters and compact aircraft… …
60zero-delivery pressure — The pressure delivered by a variable displacement pump when no services are being operated. It is the normal operating mode, with a zero stroke, when no system is being operated. The swash plate in this case has a positive angle of inclination… …
