Seal designed to seal the piston rod for a differential piston or the plunger piston in relation to the outside. A great deal is demanded of them, because they need to offer an almost perfect seal und

Hydraulic accumulator with a free-moving piston as a separator between gas and hydraulic fluid (Figure K 19) . Since there is no separating wall made of rubber, the fatigue resistance is greater than

The kind of piston ring associated with the combustion engine can also be found in mechanical engineering. As a piston seal installed in a hydraulic cylinder , it has the advantage of showing very lit

Hydraulic pump in which the pressure fluid is displaced by one or more pistons . Pistons may be arranged in a row or aligned radially or axially in relation to the drive shaft.

The radial piston motor tends to predominate with its special pneumatic motor variety. The piston motor supports high loads across all rotation speed ranges and is particularly suitable for low rotati

Hydrostatic displacement machines , displacement chamber machines , pump with banked pistons/in-line piston pump

High-precision measuring instrument which determines pressure by "weighing" it whereby the force on the piston is compared with the force exerted by calibrated weights. In order to eliminate friction,

Relationship between the piston area A K of a differential piston and the annular area A{P} R (Figure K 15):

Seal at the piston for a cylinder . With single-acting cylinders ( plunger ), the piston is only subjected to pressure on one side so only needs sealing in one direction in most cases. For hydraulic c

Slim pressure rods such as thin piston rods may buckle outwards if the compressive force F exceeds a permissible value (Figure K 12) . This value is referred to as the buckling force F K. Cylinders wi
