摘要

The valve has a housing (2) containing a valve body (3). Together these form a top (7), central (5) and bottom (8) chamber. A valve slide (4) in the center of the valve forms a channel (14) leading into the top chamber, top and bottom channels (13, 15) leading into the middle chamber and a fourth channel (16) leading into the bottom chamber. When the valve slide is moved in one direction (R) it increases the width of the top channel (13) leading into the middle chamber and the channel (16) leading into the bottom chamber and narrows the other two channels.
