Abstract
A dosing device is proposed which is designed for dosed output of a fluid. The dosing device has a block-shaped channel body, through which a dosing channel system passes. The dosing channel system has a fluid infeed opening and a plurality of fluid output openings. The fluid output openings are formed by the channel apertures of narrowed output sections of a plurality of output channels of the dosing channel system. The entire dosing channel system, including the output channels, is formed in the block-shaped channel body. The dosing channel system is preferably structured such that the flow velocity of the fluid channelled through during operation is at least substantially the same throughout with the exception of in the output sections of the output channels.
Claims19
A dosing device for dosed output of a fluid, the dosing device comprising a channel body having a dosing channel system passing through the channel body, the dosing channel system comprising:
- an input channel having a fluid infeed opening formed in the channel body to feed the fluid to be dosed;
- a first intermediate channel group fluidly connected to the input channel in a downstream direction, the first intermediate channel group having a plurality of parallel first intermediate channels, wherein each of the plurality of parallel first intermediate channels has an input and an output, the input of each of the plurality of parallel first intermediate channels being connected to the input channel at an input branching point;
- a second intermediate channel group fluidly connected to the first intermediate channel group in the downstream direction, the second intermediate channel group having a plurality of parallel second intermediate channels, wherein each of the plurality of parallel second intermediate channels has an input and an output, the input of each of the plurality of parallel second intermediate channels being connected to the output of one of the plurality of parallel first intermediate channels at a first branching point;
- a plurality of output channel groups fluidly connected to the second intermediate channel group in the downstream direction, each of the plurality of output channel groups having a plurality of parallel output channels, each of the plurality of parallel output channels having an input section and an output section, the input section of each of the plurality of parallel output channels being connected to the output of one of the plurality of parallel second intermediate channels at a second branching point, and the output section of each of the plurality of parallel output channels being directly adjoined to the input section in the downstream direction and having a cross-section smaller than a cross-section of the input section;
- and
- a plurality of fluid output openings arranged in a row beside one another to output the fluid, each of the plurality of fluid output openings being formed by a channel aperture of the output section of one of the plurality of parallel output channels of the dosing channel system,
- wherein the entire dosing channel system is formed in the channel body, and
- wherein at least one electrically actuatable control valve device is arranged on the channel body, said at least one electrically actuatable control valve device having a valve inlet and a valve outlet, and wherein the valve inlet is designed to supply the fluid to be dosed and the valve outlet is connected to the fluid infeed opening of the dosing channel system, wherein the at least one electrically actuatable control valve device is capable of selectively connecting together or separating apart the valve inlet and the valve outlet.
A dosing device for dosed output of a fluid, the dosing device comprising a channel body having a dosing channel system passing through the channel body, the dosing channel system comprising:
- at least one fluid infeed opening formed in the channel body to feed the fluid to be dosed;
- a plurality of fluid output openings arranged in a row beside one another to output the fluid;
- and
- a plurality of output channels connected between the at least one fluid infeed opening and the plurality of fluid output openings, each of the plurality of output channels having an output section and an input section, the input section being directly adjoined to the output section in an upstream direction toward the at least one fluid infeed opening, and the output section having a cross-section smaller than a cross-section of the input section, wherein each of the plurality of fluid output openings is formed by a channel aperture of the output section of one of the plurality of output channels of the dosing channel system,
- wherein the entire dosing channel system including the plurality of output channels is formed in the channel body, and
- wherein at least one electrically actuatable control valve device is arranged on the channel body, said at least one electrically actuatable control valve device having a valve inlet and a valve outlet, and wherein the valve inlet is designed to supply the fluid to be dosed and the valve outlet is connected to the at least one fluid infeed opening of the dosing channel system, wherein the at least one electrically actuatable control valve device is capable of selectively connecting together or separating apart the valve inlet and the valve outlet.
