摘要:
An electronics (100, 400) with cascaded adaptive filters for attenuating noise in a feedback path of a flow controller is provided. The electronics (100, 400) includes a signal processor (110, 410) configured to receive a flow signal (220a) from a flow sensor (220), the flow sensor (220) being configured to measure a flow rate of the pulsating flow, generate a noise reference signal (110b, 410b) from the flow signal (220a) and generate a flow rate signal (110a, 410a) using the noise reference signal (110b, 410b). The electronics (100, 400) also includes a controller (120) communicatively coupled to the signal processor (110), the controller (120) being configured to generate a flow rate control signal (120a) using the flow rate signal (110a, 410a), and a signal generator (130) communicatively coupled to the controller (120). The signal generator (130) is configured to receive the flow rate control signal (120a), generate a valve signal (130a) based on the flow rate control signal (120a), and provide the valve signal (130a) to a valve (210) to control the flow rate of the pulsating flow.

A fill valve (200) adapted for use with a pressurized fluid container includes a fill port (112) configured to be in fluidic communication with the pressurized fluid container and a fill valve member (201) configured for selectively blocking the fill port (112) and configured to be non-openable after the fill valve member (201) has been moved to a blocking position that substantially closes the fill port (112). The fill valve member (201) includes a valve member body (210) and a break-away head (220) joined to the valve member body (210) by a breakable neck (228). The breakable neck (228) is configured to break when the fill valve member (201) is moved to a substantially fully closed position in the fill port (112).
摘要:
A system for an engine (101) comprises a heat recovery system and a gaseous fuel supply system. The heat recovery system comprises a first reservoir (104) for fluid, at least one evaporator (121) for transferring heat from an engine to the fluid, a vapour expander (129) for converting fluid vapour energy into motive power, and a condenser (134). The gaseous fuel supply system comprises a second reservoir (90) for liquefied gaseous fuel and a fuel evaporator (91) for expanding liquefied gaseous fuel into gaseous fuel for the engine. The condenser (134) is in thermal contact with the fuel evaporator (91).

A waste heat recovery system (100) for an engine (101) comprises a fluid supply (104); one or more evaporators (120, 121) adapted to transfer waste heat from the engine (101) to fluid from the fluid supply (104) to heat the fluid to a superheated vapor; a condenser (134); a bypass circuit (130) in fluid communication with an outlet on the one or more evaporators (120, 121) and an inlet on the condenser (134); and an injection port (465) in fluid communication with the fluid supply (104) and the bypass circuit (130) and adapted to inject fluid from the fluid supply (104) into the bypass circuit (130) to cool the superheated vapor in the bypass circuit (130). A waste heat recovery system (100) for an engine (101) also comprises one or more evaporators (120, 121) adapted to transfer waste heat from the engine (101) to fluid from a fluid supply (104) wherein the engine (101) generates the waste heat with the fluid.
摘要:
A filter (100) with optimized fluid flows to remove one or more components from a fluid is provided according to the invention. The filter (100) includes a filtering media tube (102) adapted to remove the one or more components from the fluid while the fluid is flowing through the filtering media tube (102), and an inlet cap (104) adapted to receive and substantially uniformly distribute the fluid to the filtering media tube (102).
摘要:
An outlet valve (700) adapted for use with a pressurized fluid container includes an outlet valve chamber (701) including an upper groove (722) and a lower groove (725), an outlet valve member (760) configured to move between substantially open and substantially closed positions in the outlet valve chamber (701), and a non-return member (780) configured to be retained in one of the upper groove (722) or the lower groove (725) in a snap-fit arrangement. When the non-return member (780) is retained in the upper groove (722) the non-return member (780) does not contact the outlet valve member (760). When the non-return member (780) is retained in the lower groove (725) the non-return member (780) blocks the outlet valve member (760) in the substantially open position.
