Abstract: A lock for pivotal flaps, covers, or the like, especially for glove compartments in motor vehicles, with a curved locking member preferably rotatably supported at a pivotal part against the force of a spring, which in the locking position cooperates with its free end with a fixed locking member. The cooperating ends of the two locking members, as a result of an approximately rectangularly bent-off configuration in the form of an "L" or "U" effect a horizontal and vertical inter-engagement so that a mutual support in these two directions does not permit a disengagement of the ends of the locking members either in the upward or an opening direction of the pivotal flap.

Abstract: An injection installation for internal combustion engines, especially for mixture-compressing internal combustion engines operating with charge stratification, which essentially consists of an injection pump and of injection valves coordinated to the cylinders of the internal combustion engine; a metering mechanism is thereby arranged in each injection valve which with a feed of the injection pump supplies a metered quantity of fuel to the nozzle discharge of the injection valve while the injection pump is so constructed that it always supplies a multiple of the metered quantity of fuel independently of load and rotational speed of the internal combustion engine whereby the excess quantity of fuel flows back into the fuel tank by way of a return line connected to the injection valve.

Abstract: A drive arrangement for motor vehicles equipped with a mechanism for raising the idling rotational speed of the driving engine during its warm-up phase and with an automatic transmission whose lowest speed is adapted to be engaged by at least one servo-device; the servo-device is thereby adapted to be automatically disengaged upon actuation of the vehicle brake in the lowest speed which is coordinated to the selected drive range.

Abstract: A pneumatic controller for an injection pump of an internal combustion engine which varies the quantity of injected fuel and which includes a pneumatic actuating device acting on the quantity adjusting member of the injection pump which in the presence of a vacuum displaces the quantity adjusting member in the direction toward smaller injected quantities, and a force storage device also acting on the quantity adjusting member; a drive lever actuatable at will is provided which is operatively connected with the controller for selectively varying the torque of the engine; additional means are also provided in the controller which produce a vacuum corresponding to the deflection of the drive lever from its normal rest position while a connection exists between the additional means and the pneumatic actuating device to transmit to the latter the vacuum produced in the former.

Abstract: Wheel brake apparatus including a brake lining which is moveable into and out of engagement with a brake drum or break disk of a vehicle wheel to be braked. A measuring element is provided for detecting relative movement between the brake lining and the drum or disk. The brake lining is moved by way of a wheel brake piston acted upon by a pressure medium. In order to prevent a lock up of the brake, a controller piston is provided for controlling pressure medium flow to the brake piston in response to the detection of no relative movement between the brake lining and the brake disk or drum, which in turn corresponds to a complete braking action. In preferred embodiments, the controller piston controls a vent line communicating with the front and back of a braking control piston interposed between a master cylinder and the brake lining.
