A method for applying a spray, in particular a plant protection product, onto a field, including: detecting plants in a field section of the field with the aid of an optical and/or infrared detection unit; identifying at least one plant row in the detected field section; defining a plant area encompassing the at least one identified plant row and a weed area, different from the plant area, in the detected field section; ascertaining a plant identifier of the weed area; and applying spray onto the weed area, in particular onto the field section, depending on the ascertained plant identifier with the aid of a spraying device.

Method for applying a spray onto a field

The invention relates to a bypass valve (), in particular for an expansion machine () of a waste heat recovery system (). The bypass valve () has a housing () with a valve chamber () formed therein. An inlet (), an expander outlet () and a bypass outlet () are formed in the housing (), which feed into the valve chamber (). A closing element () is moveably arranged in the valve chamber (). A valve seat () is formed on the housing (). The closing element () cooperates with the valve seat () in order to open and close a first hydraulic connection from the inlet () to the expander outlet (). A control valve () opens and closes a second hydraulic connection from the inlet () to the bypass outlet (). The control valve () forms a first throttle point () in an open position. A second throttle point () is arranged between the valve chamber () and the bypass outlet (). The control valve (), the second throttle point () and the closing element () border a control chamber (). The first throttle point () has a greater flow cross-section than the second throttle point ().

Bypass valve for expansion machine

An electromagnetically actuated valve with a valve body which is assigned to a valve seat, is mechanically prestressed in a first direction toward a first switching position and can be adjusted by means of a magnetic actuator in a second, opposite direction into a second switching position is disclosed. The valve body has a planar contact surface which can be brought into sealing contact with a surface of the valve seat, which surface is planar at least in sections.
