摘要

A rotary slide valve presents a rotary slide (2) rotatably mounted in a control bush (1). Both parts are linked to each other by a torsion bar spring (3). A centering means (4) connected side by side with the torsion bar spring (3) acts upon the rotary slide (2). A centering spring (5) is formed therefor as a leaf spring attached to a cylindrical extension (8) of the rotary slide (2). The control bush (1) presents a conical recess (11) on its front face. A corresponding recess (10) is formed in the leaf spring part of the centering spring (5). A ball (12) is retained between both recesses (10, 11).
