Zusammenfassung:	FIELD: mechanics. ^ SUBSTANCE: device incorporates a forged casing with seats fitted therein. The said seats get sealed by the closing wedge with two-side lateral recesses. The seats are driven by the rod to move in the casing mating guides. The said guides are detachable and represent, in their cross-section, a circle with a chamfered segment. A profile, equidistant to the wedge recess profile and furnished with shoulders on the base both sides, abuts upon the aforesaid circle. The guides round parts are fitted into the casing mating holes. The guides opposite part interacts with the wedge recesses. The guides parts are unequal in size. The high part top end incorporates a disassembly element, for example, a hole. ^ EFFECT: expanded applications thanks to lower weight and reduced drag. ^ 2 cl, 3 dwg
