Abstract:
A ball (1) for valves is described, comprising a substantially ball-shaped body (2), a hole (4, 5) bored in the body (2) for fluid flow passage between the entry and exit of the valve, and a slot (10) cut into the body (2) to house a pin for ball (1) rotation. The ball (1) is produced in a single element, and the hole (4, 5) terminates in a wall (6) in which a specifically shaped opening (12) is cut to regulate the amount of fluid flow between the entry and exit of the valve.
Abstract:
The ball valve device comprises a tubular body in metal material, having a cylindrical wall conformed with cup-shaped internal protrusions to retain a ball shaped valving member, preventing the same valving member to be entrained by a fluid flowing through the valve device. The internal protrusions are performed by radially deforming inwards the cylindrical wall of the tubular body at one or more angularly spaced apart deformable areas. The tubular body provided with the ball retaining protrusions is suitable for any valve device, such as ball check valves pumping units for and/or ducts.
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 method of assembly of a rotatable flapper valve to an interior of a conduit features the ability to couple the valve plate to its axle outside of the conduit in an independent operation. The conduit is split into first and second sections each having a flared end and a pair of indentations for receipt of the valve axle. While separated, the valve axle is placed in a pair of indentations in one of the conduit sections and then the second conduit section is moved into abutting engagement such that its indentations also partially surround the axle. The first and second conduit sections are then joined by welding.

Abstract:
A throttle body for an automobile includes a throttle shaft defining a rotational axis. The throttle shaft includes deformable members integrally formed about an exterior surface of the throttle shaft. A housing includes a bore. The throttle shaft extends through the bore with the deformable member partially-located within the bore. A bearing includes an inner surface and an outer surface. The bearing inner surface forms a press-fit connection with the deformable members to substantially prevent movement between the throttle shaft and the bearing in a direction parallel to the rotational axis.
Abstract:
A valve plate assembly is provided including a plastic plate having a plurality of apertures therethrough, including at least one suction passage and at least one exhaust passage. A suction reed valve is disposed over the suction passage and an exhaust reed valve is disposed over the exhaust passage. A cylinder gasket is molded to a first side of the plastic plate and is adapted to seal around a cylinder of a cylinder housing. The cylinder gasket is recessed in a groove in the plastic plate. An end cap gasket is molded to a second side of the plastic plate and is adapted to seal against an end cap of a compressor. The end cap gasket is recessed in a groove in a second side of the plastic plate. The reed valves contact the plastic plate and are, therefore, quieter than a reed valve that is operated against a metal plate. The integration of the gasket into the recessed grooves of the plastic valve plate eliminates potential leak paths that exist with current designs. The use of a plastic valve plate also greatly reduces the weight and cost of the valve plate assembly. The valve plate assembly also provides an assembly which can be shipped to a customer in one piece for easier handling and installation.
Abstract:
A modular fuel nozzle configuration is defined which permits lower-cost manufacturing operations such as injection moulding to be employed. Also described is a method of making such a component.
Abstract:
Method for adjusting the throttling action of a valve comprising a valve body with at least one through-channel for a working medium, where the working medium is throttled by at least one valve disk which covers the throttle channel. By making use of the effect of the heat of a laser beam to change the elastic pretension of the disk, deviations from a predetermined throttling action are minimized. The laser beam is used to cause partial local melting in the minimum of one valve disk, the heat thus introduced having the effect of working at least one defined bending axis into the disk.
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.
