F15B15/22 - CPC Classification

Classification description:

Fluid-actuated devices for displacing a member from one position to another; Gearing associated therewith; Other details, e.g. assembly with regulating devices for accelerating or decelerating the stroke

Sub-classes:

F15B15/221 » {for accelerating the stroke, e.g. by area increase} 4
F15B15/222 » {having a piston with a piston extension or piston recess which throttles the main fluid outlet as the piston approaches its end position} 37
F15B15/223 » {having a piston with a piston extension or piston recess which completely seals the main fluid outlet as the piston approaches its end position} 25
F15B15/224 » {having a piston which closes off fluid outlets in the cylinder bore by its own movement} 15
F15B15/225 » {with valve stems operated by contact with the piston end face or with the cylinder wall} 23
F15B15/226 » {having elastic elements, e.g. springs, rubber pads} 54
F15B15/227 » {having an auxiliary cushioning piston within the main piston or the cylinder end face} 22
F15B15/228 » {having shock absorbers mounted outside the actuator housing} 16
