#suction

• Intake — The initial phase of the operating cycle of an internal combustion engine or pump, during which the working fluid (air, fuel mixture, or steam) is sucked or introduced into the cylinder; the pipe, port, or mechanism through which this introduction is achieved. The process is controlled by special valves to optimize volumetric efficiency and complete combustion.
• Suction — The act of aspirating, suctioning, or drawing in and its result; a structural process whereby a fluid (gas or liquid) or fine particles are drawn into an enclosed space by creating a pressure differential or a partial vacuum; (in phonetics) an intense air emission accompanying the articulation of a sound (aspirated consonant).
• Aspirated — Having been absorbed through an air current or drawn into the lungs through breathing; a sound or consonant pronounced with a strong emission of breath (aspiration); the liquid or solid product extracted from a body cavity via a medical suction pump. In a figurative sense, it describes a grand ideal or goal that a person eagerly aimed for.
• Aspiration — A strong desire, inner tendency, or grand ideal toward which a person or a collective aims (aspiration, ideal); in a technical context, it represents the physical action of absorbing or suctioning a fluid or gas by creating low pressure; in medicine, it denotes the accidental entry of foreign bodies or liquids into the airways or the controlled extraction of fluids from the body.
• Vacuum cleaner — An electrical household appliance or industrial device equipped with a motor that creates a pressure difference (partial vacuum), used to absorb dust, impurities, or liquids from various surfaces and collect them in a bag or special container; as an adjective, it describes any device, organ, or mechanical system capable of performing absorption or attraction through suction.
