Abstract: There is described herein an annular elastomer seal arranged for primary compression-type sealing capability and secondary lip-type sealing capability. The annular seal includes a pair of grooves in a radial seal face thereof, the grooves diverging with depth to form what appears as a V-shaped cut when the seal is viewed in radial cross section. When compressive stress diminishes as a result of elastomer relaxation phenomena, seepage of pressurized fluid into the grooves creates a lip seal.

Abstract: A high-pressure sealing means for two parts of deep-well drilling tools which are longitudinally movable in relation to one another consists of a wearing sealing ring (7) which is disposed in an annular groove in a first part (1) and bears against the second part (2) and prestressed radially by a pressure ring (14). The wearing sealing ring (7) has a wall surface (13) extending substantially over its axial length, which seals against the second part (2). Moreover the ring (13) is smaller than the width of the annular groove (3) of the first part (1) receiving it and is displaceable between the two sides (4,5) of the annular groove for the selective formation of a static sealing surface at one of the sides (4,5) of the annular groove. The pressure ring (14) is formed from elastomer material, has a large volume, and is gripped, compressed and deformed between the wall surface (10) of the wearing sealing ring (7) situated opposite the sealing wall surface (13) and the bottom (6) of the annular groove.

Abstract: The assembly is used with a support having a flat surface and formed with a bore extending generally parallel to but beneath the surface and with a passage extending from the bore to the surface, with a control element in the bore and pivotal therein about an axis generally parallel to the surface, and with a control rod projecting from the element through the passage beyond the surface. This rod is connected to the element and pivots therewith about the axis through an arc on pivoting of the element in the bore about the axis. The assembly comprises an elastomeric annular cuff having an inner periphery tightly engaging and secured against movement on the rod and an outer periphery engaging and slidable on the surface all around the passage and dimensioned to engage the surface all around the passage in any position of the rod. This cuff is prestressed generally parallel to the rod between its peripheries to press at the outer periphery against the surface.

Abstract: A shaft seal has an annular housing with a first and a second flange and of a hollow, frustrated cone seal ring, the apex of which is anchored liquid-tight for rotation with axial displaceably but on the shaft. The large end of the conical sealing ring forms a sealing lip which bears elastically on the inner face of the second flange which is directed toward the medium to be sealed, having essentially the shape of the frustum of a hollow. The first flange forms an annular support surface (2) which bears on the seal ring (2) between the apex shaft gripping end and the sealing lip so that the shape of the seal ring is elastically deformed.

The seals are compressed to provide a snug fit with the roller ends, and they define surfaces which develop a minimum of friction with these engaging roller ends.

Abstract: In a pump for pumping fluid having a piston with a flange, a cylinder, a gap between the cylinder and the flange, and a sealing device, an improved sealing device has an anti-extrusion ring located at a face of the sealing device opposite the fluid. The anti-extrusion ring is bonded to the sealing device and is biased to be in intimate, movable contact with the cylinder. The anti-extrusion ring is made from a material having a modulus of elasticity sufficient so that it does not extrude into the gap under the influence of the hydrostatic pressure generated during pump operation. The sealing device, or a portion thereof, has a modulus of elasticity sufficient to control the radially outward expansion of the anti-extrusion ring so that the sides of the ring do not press too tightly against and cause excessive wear of the cylinder. The anti-extrusion ring has at least one split in it, and a ring having a number of tangential-cut splits or step-cut splits could be used.
