    Abstract: A valve assembly can include a housing having multiple longitudinally spaced apart ports, a sleeve longitudinally displaceable in the housing, and at least one deflector ring configured to block flow through an annular space formed between the housing and an outer surface of the sleeve. The deflector ring is positioned longitudinally between an adjacent pair of the ports. Another valve assembly can include a housing having a port, a sleeve longitudinally displaceable in the housing, and a nozzle having an orifice in communication with the port. The nozzle is secured to the housing.

    Abstract: This disclosure presents a pump body, such as a fluid end housing used in a reciprocating pump, which provides an integral seating or engagement surface (or a valve seat integrated with the pump body) for a valve member. The integral engagement surface removes the need for a separate, replaceable valve seat and can last as long as the service life of the fluid end housing. This saves multiple maintenance services during the service life of the fluid end housing, along with the associated down time, labor costs, and material costs for the new valve seats. The integral engagement surface thus performs as an integral valve seat to the pump body. In some embodiments, the integral engagement surface may be coated, heat-treated, or otherwise modified to increase its wear resistance, such as by including one or more wear-resistant inserts to at least partially contact the valve member.

    Abstract: Secured debug of an integrated circuit having a test operation mode and a secure mission operation mode. The integrated circuit has a processing unit, a test interface through which the test operation mode is controllable, an on-chip memory which is accessible in the test operation mode and in the secure mission operation mode, and one or more protected resources inaccessible in the test operation mode. The processing unit is configured, in the test operation mode, to receive an authenticated object through the test interface, and store the received authenticated object in the on-chip memory. The processing unit is moreover configured, upon reset into the secure mission operation mode, to execute a boot procedure to determine that the authenticated object is available in the on-chip memory, authenticate the authenticated object, and—upon successful authentication—render the more protected resources accessible to a debug host external to the integrated circuit.

    Abstract: A nozzle for use with a fluid dispensing apparatus configured to dispense fluid and including a valve stem, the valve stem having a stem tip and being movable between an open position and a closed position. The nozzle includes a nozzle body and a valve seat member coupled to the nozzle body. The valve seat member includes an outer surface, an inner surface extending in a direction substantially parallel to a direction in which the outer surface extends, and a valve seat extending between the outer surface and the inner surface. The valve seat is configured to contact the stem tip in the closed position. The valve seat has a valve seat surface area, and the valve seat member is configured to maintain the valve seat surface area as substantially constant during wear of the valve seat member caused by repeated contact of the stem tip with the valve seat.

    Abstract: A valve assembly is provided, the assembly comprising a valve housing; an inlet for fluid entering the valve housing; an outlet for fluid leaving the valve housing; a flow control assembly disposed within the valve housing between the inlet and the outlet, whereby fluid entering the valve housing is caused to flow through the flow control assembly, the flow control assembly comprising a cage having apertures therethrough to provide passage for fluid passing from the inlet to the outlet, the cage having an outlet end, in use fluid flowing within the cage in a downstream direction towards the outlet; a closure assembly moveable with respect to the cage to open or close each of the apertures through the cage, to thereby control the flow of fluid through the cage; wherein the apertures in the cage extend through the cage at a first angle to the radial direction of the cage and at a second angle to the radial direction of the cage, such that, in use, fluid entering the cage through each aperture is directed into the cage at the first angle to the radial direction so as to flow around the interior of the cage and at the second angle to the radial direction of the cage so as to flow in the downstream direction towards the outlet end of the cage. A cage assembly is also provided. The valve assembly is of particular use in a wellhead assembly.
