摘要： An exhaust gas return control system for internal combustion engines is proposed, which includes an apparatus case 19 in which a servo motor 45 is disposed, which through a driving gear 47 and a driven gear 36 drives a threaded spindle 35 on which an exhaust gas valve closing member 41 is disposed which cooperates with an exhaust gas valve seat 27 on a tubular exhaust gas valve seat body 24. The apparatus case has on the side of the servo motor an air inlet of an air duct 13, 15 leading to the air induction pipe 2 of the internal combustion engine and, on the exhaust gas valve side, an exit from this air duct through which the proportionally fed exhaust gas is also led. A guiding collar 44 diverts the entry of the exhaust gas to an exhaust pipe 30 provided for the purpose. Also, in one embodiment an air valve seat body 21 radially surrounding the exhaust gas valve seat body 24 is provided, which cooperates with an air valve closing member which can be actuated simultaneously with the exhaust gas valve closing member and through which bypass air branched off upstream from a throttle valve 3 in the air induction pipe 2 can be proportionally fed.

摘要： A heating system for a motor vehicle has temperature sensors for gauging the compartment temperature as well as for gauging the temperature of the effluent hot air. These sensors are connected in series, with the compartment sensor generating the more significant control signal. The flow of heating medium, for example engine water, is regulated by a valve under the control of a regulator which compares the sensors signals with a set-point value. The valve may be cyclically actuated by pulses of fixed frequency but having a width which depends on the results of the signal comparison.

摘要： A valve arrangement, especially for controlling flow of hot water through a heating device of a motor vehicle, mainly comprises a closed housing provided with an inlet chamber and an outlet chamber communicating with each other through an opening forming a valve seat, and a valve member movable relative to the valve seat for opening and closing the opening. The arrangement includes further a flexible membrane which is clamped at its outer periphery to the housing and which forms a control chamber at the side of the inlet chamber facing away from the valve seat. The valve member is operated by an electromagnet which acts also on an auxiliary valve member in the control chamber to create during movement of the valve member toward the valve seat a higher pressure in the control chamber than in the outlet chamber and during movement of the valve member away from the valve seat a lower pressure in the control chamber than in the inlet chamber.

摘要： A fluid control valve, controlling flow of hot water through a heating arrangement for motor vehicles, comprises a pot-shaped guide sleeve in which the armature of an electromagnet is movable in axial direction, and to which a valve member is connected by a push rod, which extends through an axial bore of a magnet core fixed in the guide sleeve. The facing ends of armature and core are spaced a small distance when the valve member engages a valve seat in the valve housing between an inlet and an outlet socket. The guide sleeve is flowed through by water passing through the valve. The magnet core is clamped in the guide sleeve with a clamping force greater than the axial force acting on the core. The magnet core is positioned in the guide sleeve by first moving the core closer to the armature and then imparting to the latter a predetermined axial force in closing direction of the valve. The armature strikes the core with the great sudden impact and displaces the core until the valve member is pressed with a predetermined force against the valve seat to thus absorb the axial force. Thereafter the desired distance will be maintained when the normal closing force is applied to the armature. The valve member is normally held in open position by a coil spring and the opening stroke of the valve member is limited by a rubber disk abutting against a planar sieve disk fixed to the valve housing between the core and the valve member. The sieve disk, is supported by a bowl-shaped spacer member.

摘要： A motor vehicle is equipped with a heater assembly in which hot coolant from the engine is circulated through a first heat exchanger, normally called heater. The vehicle is also equipped with a refrigerating unit, i.e., an air conditioner, which has a second heat exchanger, or cooler, located in front of or behind the heater. Two separate temperature sensors are provided. One of these senses the compartment temperature while the other is located directly adjacent to the heater and senses the temperature of the air leaving the heater. The responsivity of this latter sensor is made substantially lower than that of the compartment sensor, i.e., its signal change per unit temperature change is lower, resulting in differential weighting. A control unit is so constructed that when the compartment temperature rises, the heater, which is normally cycled on and off in a quasi-continuous fashion, is shut off. If the temperature rises further, the controller activates the refrigerator unit and the air is cooled. If, however, the temperature now drops below the set-point without having reached the shut-off point of the two-point air conditioner control, the heater unit is re-activated. The combination of continuous heater control and two-point cooler control insures stable compartment temperatures and rapid response.

摘要： A flow control valve for controlling the flow of heat-exchange medium in a circuit of a heat-exchanger is actuated into its open position by air at subatmospheric pressure derived from the intake manifold of an internal combustion engine of a motor vehicle the climate in the interior of which is to be controlled. An auxiliary mechanism is provided which, in the event of malfunction of the pneumatically operated actuator of the flow-through valve, can be manually displaced into an end position in which it holds the valve member in its open position, thus permitting the climate-controlling arrangement to work despite the failure of the pneumatically operated actuator. The auxiliary mechanism includes a bracket-shaped rocker-arm lever tiltably mounted on the housing of the flow-through valve, and a leaf spring which, in each of the end positions of the lever, acts on the latter in such a way as to keep it in its then assumed end position. The valve housing has slots through which an energizing portion of the lever extends to the exterior of the housing of the flow-through valve to be accessible thereat for manual tilting of the lever.

摘要： An electric motor with output reduction gearing such as is provided for windshield wipers, is operated in response to a vehicle speed control system and is coupled through an electromagnetically operated clutch to a worm gear drive providing further reduction gearing that controls the accelerator pedal of a vehicle engine through a cable drum and a cable connection. When the electromagnetic clutch is released the compression spring of the accelerator pedal restores the latter and the drum and worm gear connected thereto to the engine-idling position. A resistance strip on the driven clutch member is sensed by a wiper contact to indicate or check on the position of the accelerator control and components moveable therewith.

摘要： A tubular member is adapted to communicate with an intake manifold and combustion gas conduit of a combustion engine. A housing of the valve has an interior space and a slidable valve member normally extends across and blocks the interior of the tubular member, having a portion extending into the interior space of the housing. At least one flexible diaphragm subdivides the interior space into two chambers and is fixed to the portion of the valve member. One of the chambers communicates with the atmosphere. A first and a second conduit connect the other chamber with the manifold and with the atmosphere, respectively. An electromagnetic valve is operative for alternately connecting the other chamber with the first and with the second conduit, respectively.
