Device for opening and damping a closing movement of mounted covers with - a working body with a longitudinal axis, which is arranged in a housing, wherein the working body is configured to assume three working positions coaxially to the longitudinal axis: - By means of a first pressure force on the working body in the axial direction, the working body can be released from a locking connection and, spring-mounted via a spring of the device, can be displaced out of the housing into a first working position against the first pressure force direction, - by a renewed pressure force in the same axial direction, the working body can be partially returned into a second working position in the housing, wherein the working body can be locked with the locking connection and - by continued pressure force in the same direction, the working body can be returned against the resistance of a damping element into an initial position in the housing, wherein the working body and damper are provided in a common housing characterized in that - a locking bracket on the working body can engage in the locking connection and retains the working body when engaged in the locking connection. - the locking connection is arranged on the damping element, which is damped relative to the housing and spring-mounted via a spring of the damping element, to load the damping element. - the damping element has a piston and a damping housing. - the piston is fixed to the housing and - the damping housing is displaceably damped in the housing, wherein in a rear area of the housing 20, the damping element is provided, which has the spring and damper components, - the damper housing, in its interior, has a stop against which the spring is supported, wherein against the spring pressure of the spring the damper housing can be mounted changeably in its position within the housing and - the spring of the device is arranged coaxially to the damper, which interacts with the working body - a working body with a longitudinal axis, which is arranged in a housing, wherein the working body is configured to assume three working positions coaxially to the longitudinal axis: - By means of a first pressure force on the working body in the axial direction, the working body can be released from a locking connection and, spring-mounted via a spring of the device, can be displaced out of the housing into a first working position against the first pressure force direction, - by a renewed pressure force in the same axial direction, the working body can be partially returned into a second working position in the housing, wherein the working body can be locked with the locking connection and - by continued pressure force in the same direction, the working body can be returned against the resistance of a damping element into an initial position in the housing, wherein the working body and damper are provided in a common housing characterized in that - a locking bracket on the working body can engage in the locking connection and retains the working body when engaged in the locking connection. - the locking connection is arranged on the damping element, which is damped relative to the housing and spring-mounted via a spring of the damping element, to load the damping element. - the damping element has a piston and a damping housing. - the piston is fixed to the housing and - the damping housing is displaceably damped in the housing, wherein in a rear area of the housing 20, the damping element is provided, which has the spring and damper components, - the damper housing, in its interior, has a stop against which the spring is supported, wherein against the spring pressure of the spring the damper housing can be mounted changeably in its position within the housing and - the spring of the device is arranged coaxially to the damper, which interacts with the working body
