Embodiment Construction

[0044] Figure 1 to 4 The schematic switching assembly of the gas valve unit according to the present invention is shown in the switching state next to each other. The gas inlet 1 can be identified and used to connect the gas valve unit to, for example, the gas main line of a gas cooking appliance. A gas with a constant pressure (for example, 20 mbar or 50 mbar) is provided for combustion at the gas inlet 1. For example, a gas pipeline leading to a gas burner of a gas cooking appliance is connected to the gas outlet 2 of the gas valve unit.

[0045] The gas valve unit has multiple (N) throttling sections 3, 4, 5 arranged in parallel and individually controllable for adjusting the flow of the gas volume flow. The parallel throttling sections 3, 4, and 5 are arranged between the gas inlet 1 and the gas outlet 2. In the absence of universal restrictions, in Figure 1 to 4 In N=3.

[0046] The corresponding throttle sections 3, 4, and 5 have M throttle positions 3.1-3.4, 4.1-4.4, 5....

Abstract

The object of the invention is a gas valve unit for regulating a gas volume flow to a gas burner of a gas appliance, wherein the gas valve unit has individually actuatable gas valves arranged in parallel for regulating the gas volume flow Multiple throttling segments for traffic.

Description

Technical field [0001] The invention relates to a gas valve unit for regulating the gas volume flow leading to a gas burner of a gas appliance, in particular a gas cooking appliance. Background technique [0002] For example, gas valve units of the mentioned type are described in documents EP0818655A2 and WO2004063629 A1. With this type of gas valve unit, multiple stages can be used to control the gas volume flow leading to the gas burner of the gas cooking appliance. Here, the gas volume flow has a repeatable magnitude in each stage. The flow cross-section of the gas valve unit as a whole and therefore the size of the gas volume flow is adjusted by opening or closing a certain on-off valve of the gas valve unit and thereby releasing or disconnecting the gas flow through a certain throttle opening. [0003] In addition, a patent application "Aufbau der Gasventileinheit (Structure of Gas Valve Unit)" (201002677), which has not yet been published on the filing date, describes a pos...
