Description

The invention relates to a ripple control receiver for working according to the pulse interval method Remote control systems in which a synchronous motor is coupled to a synchronous selector, the has several switching arms serving for actuation of switch contacts and in which for actuation command pulses sent to the switching contacts can be stored.

Such recipients are already known. In the case of the one known from Swiss patent specification 304,518 A ripple control receiver is a cam disk on a switching shaft driven by the synchronous motor arranged, which is provided for the actuation of a switching contact with a switching arm. A locking arm is deflected there by a cam provided on the cam disk, so that this comes into engagement with a locking pawl that can be actuated by a marking magnet. When a command pulse is received, the locking arm is again activated by the marking magnet unlocked and the locking arm falls behind the cam onto the cam disc. This arrives a nose connected to the locking arm into the area of the switching arm through which the switching arm is diverted into the 'actuation area of the switch contact. This structure of the known

ίο ripple control receiver is achieved that for actuation of the switching contact is available for a longer period of time than the duration of a command pulse stands. This in turn means that a greater amount of energy is available for actuating the contact.

In this known ripple control receiver, storage of a command pulse achieved a longer period of time for contact actuation. The intended mechanical construction However, there is relatively expensive and leads to a particularly when starting the synchronous motor correspondingly heavy load of the same, causing a strong spread of the start-up time will. The zero point shifts that occur as a result can be a cause of incorrect switching being.

Also in a remote control receiver made known by British patent specification 753 753 the synchronous motor is additionally loaded in the start-up phase; because when receiving a start impulse a rocker arm, which is in engagement with a selector disk, must pass through against a spring force the rotary movement of the dial can be adjusted.

From the Austrian patent specification 202 637, a ripple control receiver is also known in which the command pulses are stored by means of contact elements driven by the synchronous motor Cam disks are brought into a certain contact position. When starting the synchronous motor must set these cam disks in rotary motion, so that this ripple control receiver the start-up time of the synchronous motor varies as a result of the load and, as a result, also incorrect switching can be caused.

The invention is based on the object of the aforementioned in a ripple control receiver Kind of keeping the spread of the start-up time within such limits that no incorrect switching due to a zero point shift happen. This object is achieved according to the invention in that the synchronous selector is designed as a lamellar disc, of the lamellae individual by command pulses in a Storage position can be brought into which they protrude into the actuation area of the switching contacts.
