Vehicle door positioning holder

A vehicle door positioning holder for positioning a vehicle door in an open position, comprising a hydraulic cylinder and a brake hydraulically connected in a loop to the hydraulic cylinder, wherein:

• the hydraulic cylinder is configured to be connected to the vehicle door and to a chassis of the vehicle and to push a hydraulic fluid in the loop when the vehicle door is moved between the open and closed position,
• the brake comprises a first chamber hydraulically connected to the loop and a second chamber hydraulically connected to the loop, and a third chamber with a circular cross section and connected in the loop by that it in a first end is hydraulically connected to the first chamber and in a second end is hydraulically connected to the second chamber,
• the brake further comprises a ball element configured to be
• positioned in the third chamber when the hydraulic fluid is still,
• moved by the hydraulic fluid towards the first chamber as the hydraulic fluid flows in a first direction in the loop, and
• moved by the hydraulic fluid towards the second chamber as the hydraulic fluid flows in a second direction in the loop,
• wherein
• a flow resistance of the flow of the hydraulic fluid in the loop is larger when the ball element is positioned in the third chamber than when the ball element is moved towards the first or the second chamber.
