Abstract: Dispensing systems for dispensing one or more materials into a fluid flow conduit, during the conveyance of fluid through the conduit are configured to connect to a fluid conduit, such as a standard pipe of a shower arm and dispense a material into the water flow in the shower arm. The system includes a first tube member having a restrictor flow passage to provide a pressure differential, as fluid flows through the tube member. The pressure differential created within the restrictor passage by the fluid flow is communicated to a flask, to provide a pressure differential between the interior and the exterior of a flexible container within the flask. The pressure differential causes material within the flexible container to be drawn out and conveyed to the fluid flowing through the tube member. The flask may be connected to the first tube member, through an extension portion that is rotatable around the first tube member for convenient positioning.

Abstract: A fuel injector injects high-pressure gaseous fuel directly into a cylinder of an engine. A small amount of liquid fuel is used in the injector to lubricate sliding portions of the fuel injector in addition to utilizing it as a medium for transmitting driving force. The fuel injector includes a nozzle member having injection holes at its elongated end and a needle slidably disposed in an elongated center hole of the nozzle member. The needle is driven by pressure of the liquid fuel introduced into a control chamber to open or close the injection holes. The pressure in the control chamber is controlled by a switching valve which is in turn driven by an actuator such as an electromagnetic or piezoelectric actuator. The liquid fuel is injected together with the high-pressure gaseous fuel after lubricating the sliding portions between the nozzle member and the needle.

Abstract: A conventional liquid spray gun having a compressed air supply equipped with a liquid, e.g. paint, container for supplying the liquid to be sprayed onto a target surface.
