FORCE ELEMENT
Document Type and Number:
WIPO Patent Application WO/1991/013238
Kind Code:
A1
Abstract:
A force element comprises a casing (1) dismountable along its longitudinal axis (01-01) and consisting of at least two jaws (2). Inside the casing (1) is coaxially mounted a core (4) provided with flanges (5) at its ends. Between the flanges (5), along the break line of the casing (1), are mounted thrust inserts (6, 7). The thrust inserts (6, 7) have a trapezoidal cross-section in a plane perpendicular to the axis (01-01). The trust inserts (6, 7) make contact, on their lateral faces, with the internal surfaces of the jaws (2) and, on their end faces (18, 19), with the flanges (5) of the core (4). The thrust inserts (6, 7) interact wich a tubular elastic chamber (17) embracing the core (4) and connected to a source of a working medium. The tubular elastic chamber (17) embraces the core (4) on its external surface and is oriented along a spiral line.
