Abstract

Eine Leistungsregelvorrichtung (2) zum Regeln der Leistung einer Kolbenmaschine (1) weist einen an einem Stellglied (21) der Kolbenmaschine (1) angreifenden Stellkolben (18) und ein Steuerventil (19) mit einem Steuerkolben (20) auf, an welchem ein Betriebsdruck der Kolbenmaschine (1) und zumindest eine Rückstellfeder (50, 53), deren Vorspannung von der Stellung des Stellglieds (21) abhängig ist, angreift, auf. Der Stellkolben (18) und das Steuerventil (19) sind axial versetzt zueinander angeordnet, so daß sich eine Verlängerung (32) des Stellkolbens (18) durch das Steuerventil (19) hindurch erstreckt und die Rückstellfeder (50, 53) zwischen einer ersten Federaufnahme (51) der Verlängerung (32) des Stellkolbens (18) und einer dem Stellkolben (18) abgewandten zweiten Federaufnahme (33) des Steuerkolbens (20) eingespannt ist.

Figure 00000001
A power control device (2) for controlling the power of a piston engine (1) has an actuating piston (18) acting on an actuator (21) of the piston engine (1) and a control valve (19) having a control piston (20) at which an operating pressure the piston engine (1) and at least one return spring (50, 53) whose bias depends on the position of the actuator (21) attacks, on. The actuating piston (18) and the control valve (19) are axially offset from each other, so that an extension (32) of the actuating piston (18) through the control valve (19) extends through and the return spring (50, 53) between a first spring receiving (51) of the extension (32) of the actuating piston (18) and a control piston (18) facing away from the second spring receptacle (33) of the control piston (20) is clamped.
