Abstract

PURPOSE:To reduce the sliding resistance and friction resistance of sliding members in a packing by providing a core body inside the packing body which has a stiffness higher than the packing body. CONSTITUTION:In a packing having an annular groove 15, a lip 16 and an end projection 17, an annular core body 20 made of polymeric material or metal having a stiffness higher than the packing body 13 is embedded in the packing body 13. Therefore, as the stiffness of the lip 16 is increased and the lip becomes more resistant to deformation, the friction vibration between the lip 16 and a plunger can be reduced, and the sliding resistance and friction resistance of sliding members can be reduced.

According to the above-mentioned configuration, one lange (8) is a pressure oil (1).
Then, the pressure acting on the pressure oil (1) is applied to the lower end (13) of the gasket body (18) of the gasket.
At this time, pressure is applied to a), so the annular groove 05) expands, and the lip part 06) is pressed even more strongly by the plunger (81). ) and lip part (tip protrusion of 16J (+7
) comes into contact with the pressurized oil (1), which reduces leakage of the pressure oil (1). As a result, the contact 111I with respect to the plunger (8) of the tip protrusion (1η) increases. Also, due to the K-tinged pressure on the lower end surface (13a) of the packing body (08), the packing body (
1B) is compressed, so the inner peripheral surface (1B) on the packing body side
