31pump inlet check ball — A steel ball located in the plunger head or in the bottom of the accelerator pump well. The pump inlet check ball prevents fuel from escaping from the well when the throttle is opened and pressure is exerted on the fuel in the pump well by the… …
32Pump organ — The pump organ is a version of the reed organ where the player maintains the air pressure needed for creating the sound in the free reeds by pumping pedals with their feet. The portative organ is a miniature version of the pipe organ where air… …
33pressure-feed lubricating system — noun mechanical system of lubricating internal combustion engines in which a pump forces oil into the engine bearings • Syn: ↑lubricating system, ↑force feed lubricating system, ↑force feed, ↑pressure feed • Hypernyms: ↑mechanical system …
34pressure regulating valve — [1] any valve which maintains pressure at or under a certain pressure; specifically the pressure relief valve of the oil pump. [2] In a continuous injection system, part of the fuel distributor, consisting basically of a spring loaded steel… …
35pressure relief valve — A one way valve designed to open at a specific pressure to prevent pressures in the system from exceeding certain limits. In an engine s lubrication system, a pressure relief valve opens to relieve excessive pressure that the oil pump might… …
36pressure regulator — A device that reduces the pressure of the fluid from a high value to a lower value and, thereafter, maintains a constant output. The out pressure of the regulator can be adjusted. This is achieved by bypassing a portion of the fluid back to the… …
37pressure accumulator — A spherical pressure tank of about 10 mm diameter in an hydraulic brake booster. A diaphragm separates the pressure accumulator into two chambers, one contains pressurized nitrogen, the other contains hydraulic fluid supplied by the hydraulic… …
38pressure regulator — A spring loaded diaphragm type pressure relief valve which governs the pressure of the fuel delivered to the fuel injectors by the fuel pump and returning the excess to the tank. Also see system pressure regulator …
39Pump (skateboarding) — Pumping is a skateboarding technique used to gain speed without the riders feet leaving the board. This is done by selectively applying pressure to different parts of the board. Pumping can be done on flatland by turning or on a transition like a …
40pump down — [1] The act of using a compressor or a pump to reduce the pressure in a container or a system. [2] Evacuate …
