Abstract:
Grinding a machine component such as a valve component during remanufacturing, includes seating one end of the valve component in a chuck of the grinding apparatus, then contacting a steady rest with a reference surface on an outer diameter of the valve component while rotating the valve component, and then reseating the one end of the valve component in the chuck. A first valve surface on an outer diameter of the valve component is ground while contacting the steady rest with the reference surface, then a second, different valve surface on the outer diameter of the valve component is ground also while contacting the steady rest with the reference surface. The valve component is then reassembled with a hydraulically actuated device for service therein.
Abstract:
A lead hole is formed in a base material of an injection hole member with a straight punch, and then, a taper hole is formed in the base material by widening the lead hole with a taper punch. An intersection line between a virtual plane perpendicular to a central axis of the lead hole and an inner peripheral surface of the lead hole is elliptic in shape, whose major axis is directed along an intersection line between a virtual plane, which includes the central axis of the lead hole and a thickness direction axis of the base material, and the virtual plane perpendicular to the central axis of the lead hole. An intersection line between a virtual plane perpendicular to a central axis of the taper punch and an outer peripheral surface of the taper punch is round in shape.
Abstract:
A main body 110 of a component comprises a projection 120 protruding from an axis thereof in the direction of a normal, a fitting shaft portion 111 to be fitted into an opening 811 of a structure 810, and a mounting plate portion 130 including a bolt inserting hole 131a to mount and fix the main body 110 to the structure 810. The mounting plate portion 130 is formed with a notched groove 132 communicating with the bolt inserting hole 131a. The mounting plate portion 130 is fixed with a tightening bolt 820 which is screwed in the structure 810.
Abstract:
A valve (20) is provided for sealing an evacuation port (16) in a port area (18) of a wall structure (12) of a container. The valve (20) comprises a casing (22) having a shell portion (30) which is deformable from an open condition, whereat the shell portion (30) forms a chamber (32) over the port area (18), and a closed condition, whereat the shell portion (30) contacts the port area (18). When the shell portion (30) is in its open condition, gas exits from the chamber (32) through gas-releasing holes (24) in the casing (22). When the shell portion (30) is deformed to its closed condition, a port-sealing adhesive (26) adheres to the port area (18) to thereby seal the evacuation port (16).

Abstract:
A process for manufacturing a valve trim assembly. The process comprises providing a flow disk having an outer diameter, an inner diameter, and an outer disposable flow disk portion, providing a separation disk having an outer diameter and an inner diameter, wherein the flow disk outer diameter is greater than the separation disk outer diameter, stacking the flow disk on the separation disk, and removing the outer disposable flow disk portion creating a reduced flow disk outer diameter. It is emphasized that this abstract is provided to comply with the rules requiring an abstract, which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 C.F.R. §1.72(b).
Abstract:
The present invention discloses a valve integrally associated with a microfluidic transport assembly that is useful for regulating the flow of a liquid sample through an analytical instrument such as, for example, a biosensor. The valve integrally associated with a microfluidic liquid transport assembly, includes: a first rigid layer having substantially planar and opposing first and second surfaces; a second rigid layer having substantially planar and opposing third and fourth surfaces, the third surface of the second rigid layer being substantially coplanar and integrally bonded to the second surface of the first rigid layer; a first passageway defined by a groove, the groove being along the second surface of the first rigid layer and bounded by the third surface of the second rigid layer, the first passageway being adapted to flow a liquid sample therethrough, a valve seat having a substantially planar plateau surface, the valve seat being within the passageway and integrally connected to the first rigid layer such that the plateau surface is substantially planar to and interposed between the first and second surfaces of the first rigid layer; and a flexible membrane opposite the valve seat and integrally associated with a first membrane through hole of the second rigid layer, the flexible membrane having a passageway surface that is either (i) substantially coplanar to the second surface of the first rigid layer when the valve is in an open position, or (ii) bulged with a central portion thereof being substantially coplanar to the plateau surface of the valve seat when the valve is in a closed position. The present invention is also directed to methods of manufacturing of the same.
Abstract:
A control valve assembly comprising at least two control valves which may be used, for example, to throttle the air intake of an internal combustion engine. The assembly is provided with a centrally arranged, force-transmitting shaft (32). The control valves are formed by blades (15) in frames (16) produced by an assembly injection molding process. The control valve blades (15) can be molded onto the force-transmitting shaft (32). The resulting assembly can be mounted or installed as a unit. Alternatively, instead of using a single continuous shaft, shaft projections can be injection molded on the valve blades, which terminate in lugs which engage in a rotationally secure manner in sockets in an adjacent valve assembly so that the two assemblies rotate together as a unit. The resulting control valve assembly is easy to install and advantageously takes up only a little space.
Abstract:
A barstock body fluid control valve comprising a barstock body of preselected material having an inlet end and an outlet end, and a preselected cross section defining the outer walls; a through machined main flow port located eccentrically on the inlet and the outlet ends wherein the main flow port eccentric location increases the available barstock thickness at one outer wall location and decreases barstock thickness in the opposite wall.
Abstract:
A method of fabricating a module having fluid flow channels in communication with a diaphragm valve using self-bondable polyimide sheets wherein the sheets are directly interfacially bonded to one another except in the region corresponding to the diaphragm valve without using an adhesive is disclosed.
