Definitions
- the invention relates to a side channel compressor with a fan outlet.
- the invention creates a side channel compressor with flexible connection options for several consumers.
- it is provided to couple a valve unit to the fan outlet, which has at least one permanently open permanent consumer connection and at least one additional connection, which can be opened or closed as desired.
- This configuration makes it possible in a simple manner to operate one or more additional consumers in addition to a permanent consumer with the side channel compressor, the additional consumers optionally being able to be switched on or off.
- the valve unit can also be removed, so that - as usual - a permanent consumer can be connected directly to the blower outlet.
- a flow channel leads from the fan outlet to the permanent consumer connection, the flow channel being in flow connection with a plurality of additional connections via a first closable opening.
- Figure 1 is a side view of a side channel compressor with a valve unit;
- FIG. 2 shows an end view of the side channel compressor from FIG. 1;
- FIG. 3 a is a sectional view according to the section line A-A in FIG. 2 with the additional connections open;
- Figure 3b is a sectional view according to section line A-A in Figure 2 with closed additional connections.
- the side channel compressor shown in Figures 1 and 2 comprises a drive motor 10 and a compressor unit 12 with a blower outlet 14.
- a pre-assembled valve unit 16, which is actuated by a magnetic circuit, is designed so that they are connected directly to the blower outlet 14 of the compressor unit 12 can.
- the valve unit 16 can optionally be attached with or without a silencer (not shown).
- the valve unit 16 has a permanent consumer connection 18 and two additional connections 20a, 20b, so that a total of three consumers can be connected.
- FIGS. 3 a and 3 b show the structure of the valve unit 16 and its coupling to the blower outlet 14 of the compressor unit 12.
- a flow duct 22 extends directly from the blower outlet 14 to the permanent consumer connection 18.
- the flow duct 22 is connected to a valve chamber 26 via a first valve opening 24 which in turn is in flow connection with outlet openings 30 via a second valve opening 28.
- the outlet openings 30 lead to the outside and are under atmospheric pressure.
- the two additional connections 20a, 20b of the valve unit 16 open into the valve chamber 26.
- a double valve body 32 is provided in the valve unit 16 and can be moved between two switching positions via a magnetically or pneumatically controllable actuating device 34.
- the first valve opening 24 is open, while the second valve opening 28 is closed (FIG. 3a).
- the second switching position the first valve opening 24 is closed, while the second valve opening 28 is open (FIG. 3b).
- the switching state opens a second flow path from the blower outlet 14 via the valve chamber 26 to the two additional connections 20a, 20b.
- the outlet openings 30, however, are blocked off.
- the second switching state shown in FIG. 3b there is no flow connection between the flow channel 22 and the valve chamber 26, but it does exist between the valve chamber 26 and the outlet openings 30.
- FIGS. 3a and 3b It follows from the construction shown in FIGS. 3a and 3b that a consumer connected to the permanent consumer connection 18 is operated continuously, while the two additional connections 20a, 20b can alternatively be pressurized via the magnetically or pneumatically actuated valve unit 16 or not , If the consumers connected to the additional connections 20a, 20b are depressurized according to FIG. 3b, the consumers are immediately vented via the opened flow path from the additional connections 20a, 20b to the outlet openings 30. Such a ventilation is important for applications in which the system pressure in the consumer connected pipe or hose lines must be quickly dismantled.
- valve unit 16 can vary in alternative embodiments.
