Abstract

A color changer has a valve block for connecting a plurality of coating material lines to an application device. The valve block has a parallelepiped housing. The housing has a central color channel with an axial direction and contains valve bores for receiving valves and a length of a central color channel is as short as possible with a simultaneous supply of many paint feed lines. A first number of parallel valve bores open into the color channel at first openings, a second number of parallel valve bores open into the color channel at second openings on the opposite side of the color channel and offset in the axial direction with respect to the first number of valve bores. A third number of parallel valve bores open into the color channel at third openings and a fourth number of parallel valve bores open into the color channel at fourth openings.
