direct ed via the com mand valve (5) ont o clutch K1
(6).
Simultan eously the clutch B1 (7) is subjected to
overlap pressu re by the overlap r egulating va lve (2).
The pressu re in th e clut ch B1 (7) as it disenga ges is
controlled during the shift ph ase dependin g on
engine load by the modulating pressur e an d the
applying clutch pr essu re (the sh ift pressure in clutch
K1). The controlled pressure in clutch B1 (7) is
inversely proport ional to the ca pa city of t he clut ch
being en gaged. The rising shift pressure (p-S) a t
clutch K1 (6) acts on the an nular face of the overlap
regu lat ing valve (2) and redu ces t he overla p pressure
regu lat ed by the over lap regu lating va lve (2). When a
corresponding pr essu re level is reach ed a t the hold-
ing pressure sh ift valve (4), this valve switches over.
