Klin dwudzielny zasuwy, charakteryzuje się tym, że w korpusie (1), po obu jego stronach, wykonane są kieszenie w postaci owalnych rowków (6), natomiast dyski (8) osadzone są w obsadach (7) wyposażonych w owalne wypusty, które we współpracy z wymienionymi rowkami (6) tworzą zamki. Obsady (7) posiadają z jednej strony wklęsłe powierzchnie sferyczne (9) współpracujące z wypukłymi powierzchniami sferycznymi dysków (8), a z drugiej strony obsady (7) mają wypukłe powierzchnie sferyczne (13) oraz posiadają otwory, przez które przełożone są gwintowane trzpienie dysków (8) utrzymywanych w obsadach (7) nakrętkami (12), które wklęsłymi powierzchniami sferycznymi (11) współpracują z wypukłymi powierzchniami (13) obsad (7). Korzystnie, w ściankach korpusu (1) wykonane są rowki, w których zamontowane są wymienne pierścienie dystansowe (4), współpracujące ślizgowo z obsadami (7).The wedge is divided in two ways: in the body (1), on both sides, pockets are made in the form of oval grooves (6), while the discs (8) are embedded in holders (7) equipped with oval projections, which in cooperation with the mentioned grooves (6) form locks. On the one hand, the mounts (7) have concave spherical surfaces (9) cooperating with convex spherical surfaces of discs (8), and on the other hand the mounts (7) have convex spherical surfaces (13) and have holes through which threaded disc mandrels ( 8) held in the holders (7) with nuts (12), which concave spherical surfaces (11) cooperate with the convex surfaces (13) of the holders (7). Preferably, grooves are made in the walls of the body (1), in which replaceable spacer rings (4) are mounted, slidingly cooperating with the holders (7).
Part of intra-ear headphones with a concave basal concave shape with a rounded perimeter edge, a half-height perimeter strip with a circular perforation, the bevelled upper face inclined with an adjacent cylindrical projection, which is oriented inclined with respect to the body.
Seat plate for a rotating cone crusher that has one or more cooling / lubrication grooves on a surface that faces a sliding interface, the grooves are in the form of one or more spirals from a central portion of the interface and toward the periphery; set of seat plates; rotating cone crusher.
Headphones consisting of two elliptic cylindrical bodies, facing and inclined, with internal cavity, sharp elliptic recess in the outer face and lower holes: joined by an upper convex cylinder, spliced with two smaller convex cylinders that reach the middle rear area of each cylindrical body .
Hydraulic control valve, with two vertical contour plates and circular gap, and two facing and inclined cylinders in the center; the upper one with convex circular expansion, protrusions with hexagonal projections and convex upper face with central cylinder, and under the lower cylinder it has a plate between two smaller cylinders.
Wear-resistant block for use in mineral procedure equipment, solid prismatic body, regular hexagonal base and horizontal recess in the lower area of each lateral face formed by convex lower edge, medium plane 45 degrees inside, concave transverse internal edge and horizontal inner top face.
