Electrohydraulic actuating device having integrated electrical functional elements

Electrohydraulic actuation device with an electric motor and a pump driven by the electric motor for the operation of a hydraulic unit with a positioning cylinder, a piston and a piston rod serving as actuation element and projecting from a housing, wherein the electric motor and the hydraulic unit are each housed in a housing part of the housing, wherein the housing part of the hydraulic unit is separated from and sealed off from the housing part for housing the electric motor,

• wherein
• the housing has at least in the area of the hydraulic unit a lateral enlargement in relation to the longitudinal axis X of the device, beyond the circumference of the positioning cylinder and at least along a height of a stroke of the piston, for an integrated housing of electrical functional elements, sensors or control component parts directly in the hydraulic part of the housing laterally adjacent to the hydraulic unit, and that connections or receiving means for the functional elements are provided in the enlargement.
