A valve for an opening of a pressure vessel has a body member defining a fluid flow passage having an inlet and an outlet. The body member is movable between an open position in which the inlet communicates with a hollow of the vessel so that a fluid enters the inlet of the valve and is discharged from the outlet thereof, and a closed position in which the inlet is discommunicated from the hollow of the vessel and the fluid does not enter the valve. The fluid exerts during its flow through the passage a component of force upon the body member which tends to prematurely urge the latter into the closed position. An arrangement is provided for accelerating the discharge of the fluid through the outlet of the valve in the open position so as to prevent premature movement of the body member into the closed position under the action of the fluid. The above arrangement may be in form of formations reducing a cross-sectional area of the outlet of the valve, which formations may be formed in the body member and/or in a wall of a housing surrounding the body member.

A piston rod connected at one end to a piston slidably arranged in a cylinder projects with its other end through an opening in an end wall of the cylinder beyond the latter and a fork-shaped member is connected by a friction weld, that is without adding welding material or external heat, to the other end of the piston rod.
