Pressure in an installation in relation to zero pressure in a completely empty space (100 % vacuum) (according to DIN 1314) (Figure A 5) .

Hydraulic and pneumatic drive and control technology – collectively termed fluid technology – is a comparatively young specialist area of drive and automation technology that only started to become us

Back pressure valve with the task of preventing pulling loads on cylinders or motors from causing uncontrolled lowering. For this purpose, it is pre-loaded to a higher pressure than the pressure corre

Pressure that is produced after filling, e.g. on the gas side of a hydraulic accumulator or on pumps on which the suction side is pressurised.

Delivery flow pulsation

Flow rate measurement of the Bernoulli force of a flow rate on a body, e.g. a Prandtl tube ( Figure S 78 ). This is then used to measure the static pressure p 1 and the dynamic pressure p 2 and thereb

Throttle valve with adjustable throttle ( measuring throttle , A P), in which the flow remains constant through the combination of the valve with a control throttle (, A R), regardless of the changing

Also called the real dirt holding capacity. This provides information on the quantity of dirt that a certain filter can hold before a reference pressure (normally the response pressure of the bypass v

Basic design for a hydraulic drive in which the pump draws in the hydraulic fluid from a storage tank, the surface of which is open to atmospheric pressure. The oil is conveyed to the consumer via dir

Design category for seals with a block-like body and a less pronounced sealing edge. A characteristic feature is how the preload is applied not only by the sealing lips , but also by the body of the s
