In an arrangement of solenoid valves, a central plug and a printed circuit board on a control housing of a shift device of a toothed-wheel variable-speed gearbox, the printed circuit board which secures the central plug via a receptacle is clamped in directly on the control housing with the involvement of retainers for the solenoid valves.

A device is provided for influencing starting of an internal combustion engine of a motor vehicle that has an electronically controlled gearbox, an electrically acting interlock that prevents the internal combustion engine from being put into operation when a gearbox status causing a driving force connection is selected, and a starter with an electromagnetic disengagement switch that is suppliable with battery current from an ignition switch during actuation of the starter. The device has an electronic engine control unit for at least one of ignition and metering of fuel, with a communicative connection communicatively connecting the engine control unit to the gearbox control. A direct connection is provided from the ignition switch to the electromagnetic disengagement switch for supplying battery current to the electromagnetic disengagement switch without an intermediate disabling switch. A recorder records the position of an element influencing the gear-selection status of the gearbox and transmits a corresponding signal to the gearbox control. The gearbox control acts upon the engine control unit via the communicative connection to disable at least one of the ignition and the fuel metering when the element influencing the gear-selection status of the gearbox is in a position which normally effects a driving force connection through the gearbox.

In a pressure-regulating arrangement for the control pressure of a shifting arrangement of a change-speed transmission, a slide valve member is actuatable by an adjusting sleeve connected with a control member of a driving engine by way of a pressure member. A hydraulic damping device with two mutually relatively movable damping parts of the piston-cylinder-type construction is provided in which one damping part is adapted to be supported with respect to the housing and the other is actuatable by way of the pressure member and damping medium is thereby displaced against the action of a throttle. In order to improve the control behavior by decoupling the damping function from the control slide valve member, the damping device is arranged at the end face of the control slide valve member facing the pressure member and the damping part movable relative to the housing is connected with the pressure member while a damping chamber enclosed between the damping parts is connected by way of a relief valve with a space under atmospheric pressure.

A vent cap for a container of housing which accommodates a hydraulic operating medium. The vent cap includes a housing type cover which has labyrinth walls. The cover is adapted to be closed by a base insert which includes a vent passage. The vent cap is adapted to be mounted on a vent opening of the container or housing. The housing type cover is rotatably mounted on the base insert.

A locking cap for an oil gauge pipe which includes a gauge rod mounted thereon, with the gauge rod being adapted to be inserted into the oil gauge pipe. An eccentric level arrangement is provided for locking the locking cap at the oil gauge pipe while a sealing ring is pressed between the locking cap and a flange of the oil gauge pipe. The eccentric lever is mounted on the locking cap and, in a locking position, reaches under the flange of the oil gauge pipe. In a locked position, the locking cap rests against the flange with the sealing ring being interposed between an inner surface of the locking cap and the flange.
