Abstract

See full text

A valve, in particular a pilot-operated proportional directional poppet valve, has a valve housing (7) with a fluid inlet (21) and a fluid outlet (23). The fluid stream between the fluid inlet (21) and the fluid outlet (23) is adjustable by a main piston (27). A pilot valve chamber (37) provided on a rear face (29) of the main piston (27) has a pilot valve closing member (33) movable by an actuating device (69). By closing member (33) the fluid stream between the pilot valve chamber (37) and the fluid outlet (23) can be adjusted. An inlet aperture (3) is arranged between the fluid inlet (21) and the pilot valve chamber (37). A maximum volumetric flow controller (5) is in the main piston (27) in an outflow between the pilot valve chamber (37) and the fluid outlet (23).
