摘要： A control valve unit includes a valve rod sealed from a valve housing via a seal assembly. The seal assembly has a packing, received axially between a pressure sleeve and a counter bearing on the valve housing. The pressure sleeve is movably and axially mounted via a pressing element relative to the valve housing and transmits a pressing force to the pressure sleeve by a spring element to the packing. The spring element is supported on a pretensioning device with an adjustable distance to the counter bearing. The pressing force of the spring element on the pressure sleeve is adjustable and the spring element is arranged axially between first and second stops of the pretensioning device. In a preinstalled state of the pretensioning device, the spring element is supported on the first and second stops. In an operating state, the second stop is at a fixed distance to the first stop in the direction of the counter bearing. The change in the axial position of the pressure sleeve is limited by the second stop and at a distance to the pressure element in the direction of the counter bearing.

摘要： A pressure-tight stein cylinder seal and a self-energizing stein shoulder seal matching the stein cylinder seal that both use an equilaterally triangular soft ring as their sealing element, wherein their designing rules are first, by means of wedging function of a hard gland coaxial with the stein cylinder, to convert their original axial tightening force 2f respectively into a radial compression force 4f/√3 of their soft ring 04 on the stein 02 cylinder and another radial compression force 2f of their soft ring 06 on the stein 02 shoulder and ensure that the two soft rings are so compressed from a great room to a small room as to be able to pass a pressure or stress exactly to each different direction, then to cut off their off-stein corners to give their cavities an opening or give each soft ring an axial compressing allowance, and last, by means of anti-extrusion metallic C-rings without axial resistance, to close each opening to provide a full support for the sealing deformation of their soft rings compressed in their cavities.

摘要： A radial lead seal assembly of a generator and a method for sealing a radial chamber from an axial chamber of a generator using a radial lead seal assembly are presented. The radial lead seal assembly includes sealing elements disposed around a radial lead to seal an annular space between the radial lead and the radial chamber and thereby seal the axial chamber fluidically from the radial chamber. Conical springs are disposed annularly around the radial lead between the sealing elements and a junction between the radial lead and the axial lead. The radial lead seal assembly includes a nut for exerting a compressive load on the radial lead seal assembly in a radially inward direction such that the conical springs are only partially compressed.

摘要： A control valve for a double acting type Stirling engine of the type having two or more piston assemblies reciprocating in bores with each of the piston assemblies separating isolated volumes of a working gas. The control valve provides the functions of a check valve which allows an internally defined volume within the engine to be held at a low pressure near the minimum pressure of the cycle volumes. The valve may further be actuated to unload the engine to provide low starting torque and to unload the engine in case of an engine or load malfunction. The control valve further provides a controlled leakage path for working fluid flowing between the cycle volumes and the minimum pressure volume which acts as part of a pressure balancing system for the Stirling engine which maintains the volume or mass of a working fluid in a balanced condition between the cycle volumes.

摘要： A seal for a reciprocating plunger is formed of a hard polyimide plastic, rather than the relatively soft elastomers of earlier seals. The present seal has a conical section, with the tapered face fitting closely within the mating conical face of a hard metal retainer. An O-ring resides in a groove within the seal to provide low pressure sealing between the plastic seal and the metal retainer. The tapers of the seal and retainer urge the seal inwardly toward the plunger by operational pressures, thereby providing a better seal. The present seal provides greatly extended life over softer prior art seals, and will generally last for the life of the pump or other mechanism in which it is installed. Yet, the plastic material allows some flow under high pressures, allowing the seal to conform closely to the plunger surface during operation and throughout the life of the seal.

摘要： A dual rated live loaded packing system for a valve stem includes at least one thrust load assembly extending between opposing facing elements on a valve body and a packing gland, respectively, for exerting a live load through a gland onto a packing ring contained in a packing chamber around the stem. The thrust load assembly includes an elongated tension member engaging a first one of the ears at one end and a second of the ears at an opposite end. An adjustable nut is threadedly engaged on the tension member having an end facing a surface on the second ear. A spring element is mounted on the tension member between the nut and the second ear for biasing the nut away from the second ear. A cylindrical spacer is mounted on the tension member enclosing the spring element for setting up a minimum value space between the nut and the second ear. A stop washer is mounted on the tension member between the end face of the nut and the ear and includes first and second opposite stop surfaces for selective engagement with a surface on the spacer to provide different thrust bias values between the ears depending on which of the first or second stop surface is aligned to face the second ear.
