摘要: A gate valve used in pipeline transfer operations comprises a housing having a passage for conveying a fluid medium carrying solid particles, and a gate which is connected to a drive shaft for opening and closing the passage through an articulating joint made up of two elements. The first element of this joint is rigidly connected to the shaft and arranged with a clearance relative to the gate. The second element is rigidly connected to the gate and disposed with a clearance relative to the first element. Slots are provided in one of these elements to communicate the clearances with the passage for evacuating solids therefrom. The gate valve ensures tight closing of the passage by the gate and has a long service life.

摘要: A resilient wheel of a railway car includes a hub (1) with an annular projection (2) on the outer surface thereof, and a pressure disk (8), the hub and the disk being connected by bracing elements (7), and having ventilation ports (3, 9). An inner rim (4) having an annular projection (5) on the inner surface thereof is interposed between the hub (1) and the pressure disk (8). The wheel further includes resilient elements (13) some of which are reinforced and disposed between the side surfaces of the pressure disk (8) and the annular projections (2, 5) of the inner rim (4) and hub (1), while one more resilient element is disposed between the hub (1) and the inner surface of the annular projection (5) of the inner rim (4).The resilient element disposed between the hub (1) and the inner surface of the annular projection (5) of the inner rim (4) is fashioned as a silent block (14) capable of turning relative to at least one of the wheel parts (5 and/or 1) engageable therewith, the ventilation ports (3, 9) of the annular projection (2) of the hub (1) and the pressure disk (8) being located in front of the two end faces of the silent block (14).
