Disc valve
First Claim
1. A disc valve comprising:
- a housing comprising connections for a liquid or gaseous medium including at least one inlet connection and at least one outlet connection, wherein the connections end in respectively different chambers of the housing, wherein the housing has an at least basically cup-shaped distributor housing and a cover that closes off the distributor housing;
at least one valve disc which is provided with at least one first through-flow opening and which is rotatably mounted in the housing in order to fluidically connect and separate from each other the different chambers depending on its rotational position by means of the at least one through-flow opening;
a control shaft which is connected torque-proof to the at least one valve disc in the housing, wherein the control shaft or the valve disc has at least one radial projection, and wherein the housing has at least one rotation stop, which is located in a movement path of the at least one radial projection, and wherein the cover has a bearing opening through which the control shaft can be guided outwardly with a coupling end, and in which the control shaft is rotatably mounted; and
a sealing disc which has at least one second through-flow opening and is mounted torque-proof in the housing, wherein the control shaft protrudes through the at least one valve disc with an end that is located opposite the coupling end and is rotatably mounted in a bearing seat configured as a cylindrical blind hole in the center of the sealing disc that rests flat on the at least one valve disc.

Abstract
A disc valve, in particular a multi-way control valve, is provided which has a housing that has an inlet connection and an outlet connection as connections for a liquid and/or gaseous medium. The connections end in respectively different chambers of the housing, at least one valve disc, in particular a ceramic valve disc, which is provided with at least one first through-flow opening and is arranged rotatably mounted in the housing in order to fluidically connect and separate from each other the different chambers depending on its rotational position by means of the through-flow opening, and a control shaft, which is connected torque-proof to the valve disc in the housing. The disc valve is characterized in that the control shaft or the valve disc has a radial projection, and the housing has at least one rotation stop, which is located in the movement path of the radial projection.
