    • 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.

    • 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.
    • 机动车辆配备有加热器组件,其中来自发动机的热冷却剂通过通常称为加热器的第一热交换器循环。 车辆还配备有制冷单元,即具有位于加热器前面或后面的具有第二热交换器或冷却器的空调。 提供两个独立的温度传感器。 其中一个感测室温,而另一个位于加热器的正下方,并感测离开加热器的空气的温度。 后一传感器的响应度基本上低于隔室传感器的响应度,即其每单位温度变化的信号变化较低,导致差分加权。 控制单元被构造成当舱室温度升高时,正常地以准连续方式循环开启和关闭的加热器被切断。 如果温度进一步升高,则控制器启动冰箱单元并且空气被冷却。 然而,如果温度现在低于设定值而没有达到两点式空调控制器的关闭点,则加热器单元被重新启动。 连续加热器控制和两点冷却器控制的组合确保了室温稳定和快速响应。

    • 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.

    • 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.

    • 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.
    • 用于控制热水通过用于机动车辆的加热装置的流动的流体控制阀包括:壶形导向套筒,其中电磁铁的电枢可在轴向方向上移动,并且阀构件通过推杆 ,其延伸穿过固定在导向套筒中的磁芯的轴向孔。 当阀构件与入口和出口插座之间的阀壳中的阀座接合时,电枢和芯的相对端隔开一小段距离。 引导套筒通过通过阀门的水流过。 磁芯通过大于作用在芯上的轴向力的夹紧力夹紧在导向套筒中。 磁芯通过首先将芯移动到更靠近电枢的位置而定位在引导套筒中,然后将阀芯向阀的关闭方向施加预定的轴向力。 电枢以极大的突然冲击撞击磁芯,并使磁芯移动,直到阀构件以预定的力压靠在阀座上,从而吸收轴向力。 此后,当向电枢施加正常的关闭力时,将保持期望的距离。 阀构件通常由螺旋弹簧保持在打开位置,并且阀构件的打开行程受到与固定在阀壳体和阀构件之间的阀壳体的平面筛盘抵接的橡胶盘的限制。 筛盘由碗形间隔件支撑。

    • 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.
