Abstract
A vehicle door positioning holder includes a hydraulic cylinder connected to the door and a vehicle chassis, and a brake hydraulically connected in a loop. The cylinder pushes hydraulic fluid in the loop when the door is moved. The brake includes first and second chambers hydraulically connected to the loop and a third chamber connected in the loop at respective ends to the first and second chambers. The brake has a ball element in the third chamber when the hydraulic fluid is still, moved towards the first chamber as the hydraulic fluid flows in a first direction, and moved towards the second chamber as the hydraulic fluid flows in a second direction. A flow resistance of the hydraulic fluid is larger when the ball is positioned in the third chamber than when the ball is moved towards the first or the second chambers.
