DETAILED DESCRIPTION OF THE INVENTION



[0010] The cam disc (4) that is the subject of the invention will now be tried to be explained in detail. There is a D-like form (4.1.) on the cam disc (4) that enables to be mounted on the tap (1) and that enables the cam disc (4) to be rotated with the tap shaft (2). This form (4.1.) is the same with the D-shaped form (2.1.) of tap shaft (2). By this means, the montage operator can mount the cam disc (4) that is the subject of the invention easily on the right direction. The neck length (4.2.) of the cam disc is narrower than the distance between two grooves (2.2.) on the tap shaft (2). There is segment (3) on the first groove (2.3.) on the shaft so as to prevent the forward movement of the cam disc before the cam disc (4) is mounted on the shaft. A second moon segment (8) is placed to the second groove (2.4.) of the tap shaft so as to prevent the cam disc (4) from going off upon giving the tap shaft (2) forward. By this means, the cam disc (4) is connected on the tap shaft (2) in a rigid way. The inner diameter (4.5.) of the cam disc passes into the outer diameter (9.1.) of the cap (9) during connecting. By this way, the cap (9) makes bedding to the cam disc (4).

[0011] The tap shaft (2) is given forward so as for the ignition module (6) going to the burners to be operated. The bottom surface (4.3.) of the cam disc (4) operated synchronized with the tap shaft (2) starts to press towards the sheet (6.1.) of the burner ignition module (6) and by this means ignition is performed by means of turning on the contact. At the same time, pressing process is performed to the top round surface (1.1.1.) of the safety valve press pin (1.1.) upon the pressing process and gas passage is enabled by means of providing opening of the safety valve. There is an angled surface (4.4.) at the end part of the bottom surface (4.3.) of the cam disc (4) during the pressing process. The angle of this angled surface (4.4.) may be between 10 and 60°. The angle of the angled surface (4.4.) of the cam disc that is the subject of the invention is preferably 15°.

[0012] When the tap (1) is in the turned off position, the cam (4.6.) of the cam disc (4) is in the pressing position to the sheet (7.1.) of the ignition module (7) to provide the required electricity for the lamp. This ignition module (7) is operated reversely unlike the other ignition modules, meaning that the contacts do not transmit electricity current when the sheet (7.1.) of the ignition module is in the pressing position.

[0013] The cam (4.6.) of the cam disc (4) ends the pressing process to the sheet (7.1.) of the lamp ignition module (7) upon the rotating process of the tap (1) from turned off position to turned on position is started and the contacts of the lamp ignition module (7) light the lamp of the furnace bottom part by means of completing the electricity circuit.

[0014] So as to provide the electric grill part of the tap (1) to be operated, the tap is rotated about 62° clockwise and the back surface (4.7.) of the cam (4.6.) of the cam disc (4) is provided to press on the sheet (5.1.) of the ignition module (5) to make electricity ignition for the grill. The angle (4.7.1.) of the back surface may be between 20° and 80°. This angle (4.7.1.) is preferably 62°. By this means the electricity current is enabled to reach to the burner and the electric grill is provided to be flamed.

[0015] Another feature of the cam disc (4) is that, there are two holes (4.8.) allowing for the adjustment of the adjustment screw (10) on the tap (1). The adjustment screw (10) on the tap is provided to be adjusted by the help of an appropriate screwdriver through these holes (4.8.).

[0016] The invention is suitable for use in all gas taps in the domestic cooking devices.
