  • Patent number: 9122277
    Abstract: Disclosed is a flow regulator, especially for insertion into a jet regulator in an outlet fixture, comprising an insertion member that is penetrated by at least one flow duct in an axial direction as well as a throttle element which forms a control gap along with the insertion member in order to allow a fluid to penetrate into the at least one flow duct. The aim of the invention is to create a flow regulator which allows for significantly greater durability during use while offering maximum ease of operation when fluid is discharged. Said aim is achieved by a flow regulator in which the throttle element is embodied as a dimensionally stable throttle cap that is supported in relation to the insertion member via an elastic spring element.

  • Patent number: 9115610
    Abstract: A variable engine valve timing control system has a cam phase actuator, with first and second actuator ports, to adjust a rotational phase of a camshaft relative to a crankshaft. A first control valve selectively couples the first actuator port to either an engine oil pump or a first valve port. A second control valve selectively couples the second actuator port to either the engine oil pump or a second valve port. Separate check valves prevent oil flow backwards through the first and second control valves from the cam phase actuator to the engine oil pump. In one implementation, the first valve port and second valve port are connected to a fluid reservoir. In another implementation, the first valve port is connected by another check valve to the second actuator port, and the second valve port is connected by a further check valve to the first actuator port.
