Definitions

  • the invention relates to a gas tap for controlling a Gas burner especially for household cooking and Heaters, with one through the tap axis over one penetrating the cock plug displaceable in the axial direction Tappet influenceable thermoelectric Safety valve.
  • thermoelectric safety valves Gas taps with thermoelectric safety valves are known. With these gas taps, the opening of the thermoelectric safety valve by axial Pressing in the tap axis. That to the burner flowing gas is ignited and heats a thermocouple, whose thermal current excites an electromagnet and the safety valve in the open position for so long records how the thermal current flows. With this arrangement is an indentation of the tap axis to open the Valve seat indispensable with the tap axis as long must remain depressed until excitement and liability of the safety valve automatically opens the valve seat holds.
  • the stroke movement of the tap axis is used of thermoelectrically secured gas valves considered very easy to use, too the distance between the toggle and the device cover must be greater than for functional reasons the total stroke of the tap axis, which in turn optically in Scope is assessed as detrimental.
  • the object of the invention is that which is necessary anyway Rotary movement to regulate the gas valve Tap axis to use that at the same time opening the thermoelectric safety valve without any Stroke movement of the tap axis occurs, a destruction of the Functional parts excluded due to length or stroke tolerances and the gas flow safety of the gas tap is given during part of the ram stroke movement.
  • This object is achieved in that an axial feed movement by rotating the tap axis of the plunger via a cam-like one in particular Slope curve can be generated, the location of the The tap axis remains unchanged in the axial direction.
  • the gas tap consists of a housing 1, which with is equipped with a gas inlet and outlet, a rotatably mounted chick 2, a safety valve 27, 27a and controls described in more detail below with compensation mechanism and safety sealing seat.
  • the chick 2 is penetrated in the middle by a plunger 3, which is caused by the axially generated stroke when the Tap axis 8 via the toggle 8c, the valve seat 27a of the safety valve opens.
  • the drive of the switching mechanism consists of the Tap axis 8, which is in a guide bore 6a of the on the housing 1 attached front bottles 6 is mounted, wherein the ring 9 prevents an axial stroke movement of the tap axis 8.
  • the tap axis 8 On a first longitudinal plane at the rear end the tap axis 8 is a slot-shaped recess 8a attached, in which a wrench-like profile part 12 engages, can slide axially and with everyone Rotation of the cock axis 8 is rotated radially.
  • a finger-like arm 8b is attached, which at the same time in a chick-taking slot 2a of the plug 2 engages and the rotation of the tap axis 8 transfers to the chick 2 to the different functional positions to reach the gas tap.
  • the profile part 12 is equipped with a guide hole, in which stores a compensation mechanism 10, 11 and 14. At the same time, the front end of the plunger is supported 3 in the guide bore of the profile part 12.
  • the slide pin 13 slides by turning the tap axis 8 via a radially rising cam-shaped gradient curve 7a of the socket 7, (see Figure 4) whereby the Profile part 12 is moved axially and thereby simultaneously pushes the plunger 3 in the axial direction.
  • spring forces are adjusted accordingly, spring 11 is stronger than spring 18.
  • the sliding pin falls 13 by the back pressure of the spring 18 with the Tappet 3, the O-ring 22 and profile piece 12 in its Starting height of the closed position back, the Gas flow to the gas outlet of the gas tap released at the same time becomes.
  • the burner can be ignited using the thermocouple 31 due to the flame heating on the sensor Thermal current for that until then by external electrical current open safety valve 27 generated and thereby the open position of the safety valve takes over as soon as the external electrical current is switched off is.
  • the gas tap At the initial height of the sliding bolt 13 can be turned counterclockwise by further rotation the gas tap the different functional positions up to the end stop without axial displacement of the Reach tappet 3.
  • the switching axis 8 in the closed position is the gas flow shut off by chick 2, the burner extinguished, the sensor of the thermocouple 31 cools and thus also closes the valve seat 27a of the safety valve 27.
