Abstract: The regulator comprises a bypass valve which is parallel to a throttle arranged in a suction pipe and which is actuated by a servomotor. In order to adapt it to the different running states of the engine, the maximum opening cross section area (14, 114, 214, 314) of the bypass valve (1, 101, 201, 301) is determined by a stop (lift rod 27, 127, stop sleeve 227) which may be moved by an actuator (24, 124, 224) and which reduces the travel of the valve body (29, 129, 229, 329) in relation to at least one running parameter of the engine, such as running temperature, time interval from cold start, number of combustion chambers operating.

Abstract: A valve assembly (10; 110) of novel configuration is associated with the main air induction passage of a fuel-injected, spark-ignited, automotive internal combustion engine for the purpose of regulating the idle air flow. The valve assembly has an inlet (20) connected upstream of the throttle and an outlet (22) connected downstream of the throttle. A pintle (30) controls the restriction that the valve assembly imposes on the idle air flow. The valve assembly is controlled by the engine computer (102) selectively energizing a solenoid (72) on the assembly. In one embodiment (10) the solenoid armature (62, 92) controls flow through another flow path (50) of the valve assembly that parallels the idle air flow path (24). A movable internal wall (36, 38) divides the valve assembly's body into two variable volume chambers (46, 48). One chamber (48) forms part of the idle air bypass (24) while the other (46) forms part of the parallel flow path (50). The one chamber is essentially at manifold vacuum while the other is regulated by a bleed valve (52) and two orifices (60, 70) in the parallel flow path. Positioning of the movable wall positions the pintle. In a second embodiment (110), one chamber (48) is communicated with the idle air flow path (24) by an orifice (138), and the other (46) is communicated with the idle air flow path (24) by constructing the pintle from a hollow tube (130) containing the two orifices (60, 70) and placing the bleed valve (52) external to the tube for direct action with one (60) of the orifices. When the solenoid is not energized, the pintle is positioned to allow full idle air flow.

Abstract: In a rotating actuator, especially with the use of plastic intake pipes and connections, noise is produced as a result of turbulence which should be prevented. To this end there are plane boundary surfaces (25) at the throttle aperture (13) and another (26) at the outlet aperture (14). In addition, there are in the intake stub flow-assisting transitions with a convex and a concave region (40, 41) of a truncated conical taper (24) towards the boundary surfaces (25) and in the outlet stub (6) there is a flow-assisting transition with a convex and concave region (42, 43) towards the truncated conical broadening (27) of the outlet stub (6). The rotating actuator is especially usefull to control the idling speed of internal combustion engines.
