摘要： A mud pulser for generating pulses in a fluid flow in a wellbore. The mud pulser has a valve housing having an uphole opening for receiving fluid flow, and a piston valve situated in a piston chamber is longitudinally moveable between an open and closed position by closing and opening a pilot port downhole of the uphole opening and in fluid communication with the piston chamber. A first channel extends in the sidewall of the valve housing and fluidly connects the uphole opening and the pilot port. One or more fluid egress ports are in communication with the piston chamber. A metering orifice may be inserted in said one or more fluid egress ports for first channel. Opening and closing the downhole pilot port moves the piston valve and thus opens and closes the uphole opening thereby generating pressure pulses in the fluid flow. A downhole valve is further disclosed.

摘要： A soft-opening valve, such as for a refrigeration system, includes a valve body having an inlet, outlet, main passage between the inlet and outlet, and a first valve surface movable in the main passage to control fluid flow from inlet to outlet. The valve also includes a fluid chamber separated from the main passage, and which receives fluid flow from secondary passage(s). A vent passage is provided in the chamber, and a second valve surface is movable in response to fluid pressure in the chamber to open or close the vent passage. When the secondary passage(s) is/are opened to supply flow to the chamber, the opening and closing of the vent passage with the second valve surface operatively controls the first valve surface to move between a partially-open low-flow position and a fully-open full-flow position. When the secondary passage(s) is/are closed, the soft-opening valve is in a closed state.

摘要： The 4-way valve used to control the operation of a pneumatic motor can be pneumatically operated such as by a pilot valve. The pilot valve (20) works by creating a restriction at the high-pressure air/signal port (22) regardless of the pressure drop upstream of the pilot valve (20) while still allowing for adequate flow once the valve (20) is actuated. An additional slide valve (24) is added to the pilot valve (20) that restricts the inlet 30 of the pilot valve (20) above the poppet valve (28) that creates a pressure drop, see Figure 3. The extra pressure drop forces the valve (20) to snap open once the actuator pin (32) contacts the poppet valve (20) to create the hysteresis. Once the valve (20) snaps open, the slide valve (24) moves to uncover the high-pressure ports (22), removing the restriction to ensure that the main 4-way (10) fully actuates.
摘要翻译：用于控制气动马达操作的四通阀可以通过先导阀气动操作。先导阀（20）通过在高压空气/信号端口（22）处产生限制而工作，而不管先导阀（20）上游的压降如何，同时一旦阀（20）被致动就允许足够的流量。附加的滑阀（24）被添加到先导阀（20），其将先导阀（20）的入口30限制在产生压降的提升阀（28）上方，参见图3.额外的压降力一旦致动器销（32）接触提升阀（20）就产生滞后，阀（20）就会卡扣。一旦阀（20）卡扣打开，滑阀（24）移动以露出高压端口（22），去除限制，以确保主4通（10）完全致动。

摘要： A regulator (100) having a valve body (102) defining a flow-path (108) for a fluid and having a valve seat (104), an actuator casing (122, 124) coupled to the valve body, a control member (130) disposed within the actuator casing and adapted for displacement relative to the valve body and the valve seat for regulating a flow of the fluid through the flow-path by moving between an open position and a closed position wherein the control member engages the valve seat, and a spring (193) operatively coupled to the control member and biasing the control member toward the open position. The control member includes a surface facing the valve seat that is recessed. The recessed surface may be a counter-bore (148), or may have a convex shape, conical shape, or other appropriate recessed surface. So configured, the regulator displaced improved stability in high inlet pressure, low output pressure, high flow rate implementations.
