  • Patent number: 10767570
    Abstract: A regulating device for an internal combustion engine includes a housing in which is formed an exhaust gas recirculation pipe which opens into an intake pipe, and a regulating element eccentrically mounted on a shaft. The regulating element includes a first surface, a second surface, and guide ribs arranged on the second surface so that an exhaust gas flow flows into the intake pipe when the exhaust gas recirculation pipe is opened. In a first end position of the regulating element, where the intake pipe is at throttled upstream of an opening of the exhaust gas recirculation pipe, a normal vector of the first surface points to an upstream side of the intake pipe. In a second end position of the regulating element, where the exhaust gas recirculation pipe is closed, a normal vector of the second surface points to the exhaust gas recirculation pipe.

The flow control device has a fluid flow controller (30) between the body portion and the control portion in the form of at least one annular ring (35), disposed in a recess in one of the body portion and the control portion (10). The fluid flow controller (30) defines a leak path through the device that is opened and closed by a pressure differential acting across the annular member. Typically the application of a pressure differential across the fluid flow controller moves the ring(s) to one end of the recess and reduces the cross sectional area of the leak path available to the fluid, thereby diffusing the fluid flow through the orifice (8).

  • Publication number: 20140103235
    Abstract: A flow control valve comprises a valve seat (1) having a valve port (121) in its valve chamber and a valve rod (2) opening or closing the valve port (121). A sleeve protrusion part (122) projects upward from the valve port (121) in an axial direction thereof. The valve rod (2) is tubular and is cylindrical at the lower end. An open slot (3) matching with a flow curve is provided in the circumferential side wall of one of the sleeve protrusion part (122) and the lower end of the valve rod (2). One of the sleeve protrusion part (122) and the lower end of valve rod (2) is inserted into or extracted from the other to disconnect or connect the open slot (3) with the valve port (121). The structural design of the flow control valve can balance the refrigerant pressure on the valve rod (2) in the axial direction while ensuring that the required flow curve can be obtained.

  • Patent number: 8662035
    Abstract: An oil control valve is disposed in fluid communication between an oil supply gallery and an oil control gallery of an oil control system. The oil control valve has a first position that prevents flow of oil from the oil supply gallery to the oil control gallery and permits flow of oil from the oil control gallery to a downstream drain line, and a second position that permits flow of oil from the oil supply gallery to the oil control gallery and prevents flow of oil from the oil supply gallery to the drain line. An oil bypass passage is disposed in fluid communication between the oil supply gallery and the oil control gallery, and is disposed to bypass the oil control valve. The oil bypass passage has first and second oil flow constriction regions, and an intermediate volume disposed between the first and second oil flow constriction regions.
