摘要： A bellows is comprised of a unitary body formed of relatively thin annular walls, open at one end and closed at the other. The walls are constructed and arranged as a spiral groove, whereby the bellows can be fabricated from plastic by injection molding in a relatively inexpensive fashion. The bellows can be formed of two layers joined to one another, a backup layer formed of metal or plastic and a protective layer formed of plastic such as PFA and PVDF.

摘要： A pulsation damper for a pumped liquid system has a housing with two axially identical hollow halves which, when joined at their flanges, form a substantially cylindrical cavity. Each housing half has a port on its longitudinal axis for fluid communication with a liquid chamber and a gas chamber defined by a flexible non-porous member. A pressurizing valve is provided, in a manual embodiment, for manually increasing or decreasing pressure in the gas chamber. An automatic pressure compensator is provided in an automatic embodiment and is so sized and configured as to be insertable and removable from the housing of the pulsation damper through the port on the end of housing. Provision is also made for modularly adding volumes of air to increase the effective gas chamber volume.

摘要： A valve assembly for fluid pressure regulation provides freedom from static pressure creep by eliminating distortions and stresses normally introduced to valve parts during assembly of the regulator. A floating valve seat permits normal installation of a valve seat housing in the regulator body with no transfer of stress or distortion to the valve seat. Thus statis pressure creep, normally attributable to micro distortions of the valve seat, is avoided. Options are also provided to install the floating valve seat directly in a regulator body without the valve seat housing.
摘要翻译：用于流体压力调节的阀组件通过消除在调节器组装期间通常引入阀部件的变形和应力而提供无静压蠕变。浮动阀座允许在调节器主体中正常安装阀座壳体，而不会向阀座传递应力或变形。因此，避免了通常归因于阀座的微小变形的状态压力蠕变。还提供了将浮动阀座直接安装在没有阀座壳体的调节器主体中的选项。

摘要： A fluid pressure regulator provides features which enable an extended regulator life in high pressure service. Dual flexible diaphragms provide chemical resistance in contact with the working fluid and abrasion and fatigue resistance in contact with a backup plate and piston assembly. The backup plate has a bore which is sufficiently long and close fitting with the piston so that axial alignment is assured and there is minimal tendency for the piston to become cocked within the bore. Provision is also made for preventing fretting corrosion between the piston and the backup plate by coating at least one of the surfaces, if necessary, to assure that dissimilar metals only are in contact in that couple. Seals between the regulator housing body and the diaphragm and between the valve stem and diaphragm may be provided by resilient seal rings or by annular protrusions integrally formed on one or both of the diaphragms.
摘要翻译：流体压力调节器提供了能够在高压服务中延长调节器使用寿命的特征。双柔性隔膜提供与工作流体接触的耐化学性，并与支撑板和活塞组件接触时的耐磨性和抗疲劳性。支撑板具有足够长且与活塞紧密配合的孔，使得轴向对准得到确保，并且活塞在孔内被起动的最小倾向。另外还要防止活塞和支承板之间的磨损腐蚀，如果需要，通过涂覆至少一个表面，以确保不同金属在该对中仅接触。调节器壳体和隔膜之间以及阀杆和隔膜之间的密封可以由弹性密封环或整体地形成在一个或两个隔膜上的环形突起来提供。

摘要： A check valve cartridge for a fluid pump, the check valve cartridge including: a valve seat; a flap valve member seated on the valve seat, the flap member having a first portion movable toward and away from the valve seat; a bumper seated on the flap member, said bumper member for biasing the first portion of the flap valve member toward the valve seat. The check valve cartridge also including a stop member located on the bumper, between the stop member and the flap member; and fastening means for joining the base, flap member, bumper, and stop member to form the integral valve cartridge. The check valve cartridge is seated in a recess formed in the pump housing and is located between the pump housing and a flow manifold.

摘要： Apparatus for drying damp carpet and carpeting materials is disclosed. The apparatus includes a blower (22) for blowing air under the carpet, and a clamp (24) affixed to the blower (22), for securing the carpet to the blower (22). The blower (22) includes a blower housing (26) with a head (28) having air intake openings (32) and a sleeve (30) that forms an air outlet opening (36); and a powered fan (34) attached within the head (28) of the blower housing (26) for blowing air out of the sleeve opening (36). The clamp (24) comprises a mounting bracket (44) affixed to the blower housing (26), a rod (46) slidably coupled to the mounting bracket (44) and a restraint mechanism (54) for preventing the rod (46) from sliding upward away from the carpet. The restraint mechanism (54) is attached to the mounting bracket (44). The clamp (24) also includes a foot ( 48) attached at the lower end of the rod (46) for holding the carpet against the sleeve (30) of the blower housing (26). The apparatus can be used to dry carpeting materials simply by placing an edge of the carpet between the clamp foot member (48) and the housing sleeve (30), applying force to the clamp rod (46) in the direction of the housing sleeve (30), and securing the restraint mechanism (54) such that the clamp (24) holds the carpet in place. The blower (22) can then be activated to force air from the sleeve (30) underneath the carpet. Another aspect of the invention is a clamp (24) adapted to be attached to a blower (22), for holding the carpet as described above.
