Abstract: The present invention relates to a non-return valve that can be configured for use anywhere along a molding material flow path in a molding system. The non-return valve of the present invention includes an improved means to restrict the backflow of melt therethrough during injection. In particular, a spigot-seal is configurable, during injection, between overlapping, closely-spaced, and mutually parallel complementary male and female spigot portions that are configured between complementary valve members. The spigot-seal advantageously maintains an effective backflow restriction even in the eventuality of transient movement between the spigot portions during injection. Preferably, the non-return valve of the present invention is also configured to include a means for mutually aligning and/or guiding the complementary valve components that ensures a proper alignment between the complementary spigot portions, and may also serve to improve the function and longevity of a face-seal, when present. The non-return valve of the present invention provides particularly advantageous utility when configured for use in a barrel assembly of an injection unit for the injection molding of a metal alloy.

Abstract: The invention relates to a hydraulic valve play compensating element, for example for generating valve play compensation for a gas exchange valve in a valve operating mechanism of an internal combustion engine, having a piston housing (3) in which a piston (2), which is elastically supported against the piston housing (3) via a piston spring (9), is guided in a movable fashion, in which the piston (2) has a low-pressure space (7) which is connected via an axial opening (6) in a piston head (4) to a high-pressure space (8) which is enclosed by the piston housing (3), and having a control valve (12, 12') which has at least one control valve closing element (13) which can bear in a seal-forming fashion against a valve seat (21), the latter surrounding the axial opening (6) on a piston head underside (16), and comprises a control valve spring (14) which is preloaded in the opening direction, wherein, in the event of a collapsing movement between the piston (2) and the piston housing (3) when the gas exchange valve is actuated, the control valve closing element (13) can be acted on hydraulically in the closing direction by means of a build-up of pressure in the high-pressure space (8). In order to improve the valve play compensating element in such a way that it has a simpler, more cost-effective and flow-enhancing-design and at the same time permits reliable operation which is unsusceptible to tolerances, the control valve spring (14) is embodied as a spring element which is arranged in the high-pressure space (8), is radially spaced apart from the axial opening (6) and from the control valve closing element (13, 13') and is supported between the piston head underside (16) and a control valve holding element (15, 15') which is guided in the high-pressure space (8) in an axially movable fashion with a delimited actuating travel (20), holds the control valve closing element (13, 13') and is provided with an oil passage (19).

Abstract: A flexible size diffuser grid assembly formed up of individual sparger units for use as a noise abatement device to reduce the fluid pressure in a predetermined manner to substantially reduce the aerodynamic noise and structural vibrations produced by a fluid moving therethrough. The sparger grid assembly is formed in a window pane grid-like arrangement of individual sparger pane units, each of which are mounted in a support frame, and each of which utilize individual stack of flat plates, the plates respectively having inlet slots and outlet slots, and interconnecting plenums, to create a series of passageways to substantially subdivide the flow stream of steam into smaller portions to reduce fluid pressure. The individual sparger units can be formed of a standard size, or instead formed of custom sizes, and greater or less numbers of individual window pane sparger units can be used in the frame, depending on the given end-use application.

Abstract: A ball valve for fluids comprises a body (11) provided with an inlet and an outlet (12, 13) and with an inner chamber (14) in which a ball element (15) having a main communication passageway (17) passing through the ball element itself is rotatably received. The ball element is rotatable between an angular position at which the valve is completely closed, said passageway being disposed substantially transverse to the inlet and outlet, and an angular position at which the valve is completely open, said main passageway being aligned with the valve inlet and outlet to create a communication therebetween. The ball element (15) comprises a secondary communication passageway (19) of a reduced section disposed laterally of said main communication passageway. The secondary passageway is designed to bring the valve inlet and outlet into communication with each other when said ball element is in a range of intermediate angular positions between said completely open and completely closed positions.

Abstract: A rotary ball valve assembly for a rotary ball valve comprises a rotary closure element and an impedance assembly. The closure element is rotatable about a rotational axis, and has a through-bore defining a flow inlet and a flow outlet. The impedance assembly is positioned, at least in part, within the bore of the closure element. The impedance assembly includes a plurality of flow passages therethrough. An inlet and/or outlet of two or more of the flow passages is elongate and arcuate so that, in use, as the closure element rotates, the arcuate elongate inlet and/or outlet of each flow passage which is exposed is fully or substantially fully opened.

Abstract: A valve (2) has a body (4) defining a flow inlet (6), a flow outlet (8) and a valve chamber (10). A compression coil spring (24) is contained within the chamber (10) and its coils (32) divide the inlet (6) from the outlet (8). One end of the spring (24) is seated against a reaction block (20) and an actuating rod (16) extending into the valve chamber (10) bears on the block enabling it to be lowered or raised. This action causes the size of the helical gaps (34) between the coils (32) of the spring to be altered which adjusts the flow of fluid through the valve.

Abstract: A precision modulating globe valve for controlling the flow of a fluid from zero to a maximum flow rate. The valve plug of the globe valve includes at least one flow modulating channel recessed from the outer surface of the valve plug. The outer surface of the valve plug engages a sealing member positioned along the inner surface of the valve port. The sealing member provides a fluid-tight seal between the outer surface of the valve plug and the valve port. The flow modulating channel is recessed from the outer surface of the valve plug from a minimum flow end to a maximum flow end. The radially recessed area of the flow modulating channel increases from the minimum flow end to the maximum flow end, such that as the valve plug moves past the stationary sealing member, an increased flow rate is created through the valve port.
