Patent number: 10564652Abstract: A valve includes a body defining first and second connection points, a valve slider, a spring, and a choke. The valve slider delimits first and second apertures to enable conduction of pressurized fluid from the first connection point to the second connection point via the first aperture, and is configured to move in an adjustment direction to close the first aperture. The choke is configured to enable conduction of pressurized fluid from the first connection point to the second connection point via the second aperture and via the choke. A first control point is defined between the choke and the second aperture. A second pressure at the first control point and a force of the spring pushes the valve slider in the adjustment direction, and a first pressure at the first connection point pushes the valve slider against the adjustment direction.Type: GrantFiled: November 14, 2016Date of Patent: February 18, 2020Assignee: Robert Bosch GmbHInventors: Thomas Mueller, Konrad Schneider
