Turbulence of the jet ejected from the nozzle hole is suppressed. The nozzle includes a shaft body having a center axis, a liquid guide path located inside the shaft body and extending along the center axis, a liquid chamber disposed at a distal end portion of the liquid guide path the liquid chamber having a nozzle hole. The nozzle hole is located at the distal end portion of the liquid chamber, extending along the ejection axis that extends in a direction different from the center axis. The nozzle has an inlet portion having a smaller diameter toward the downstream, and a guide portion connected to the downstream of the inlet portion to guide the liquid to an opening.

A spray nozzle assembly for directing thin, straight line, high pressure liquid spray onto moving steel slabs for penetrating and removing scale buildup in steel processing operations. The spray nozzle assembly includes a liquid inlet defined by an upstream strainer and a downstream high impact attachment tube for accelerating liquid flow. A one-piece multi-stage liquid straightening vane segment is disposed within a central liquid flow passage of the nozzle assembly for more effectively reducing liquid turbulence of the high pressure liquid flow with resultant improved control in the tightness of the thin, flat spray panner. The one-piece vane segment further is adapted for efficient assembly and replacement in the spray nozzle assembly without the need for handling and precise alignment of a plurality of individual vane elements.

To adsorb an adsorbate rapidly on a heat storage material with good energy efficiency. A chemical heat storage device includes an adsorbate, a heat storage material, and a sprayer. The adsorbate is in a liquid state at normal temperature. The heat storage material releases heat of adsorption in response to adsorption of the adsorbate on the heat storage material and stores the heat of adsorption in response to desorption of the adsorbate from the heat storage material. The sprayer sprays the adsorbate on the heat storage material in a heat release period of causing the heat storage material to release the heat of adsorption. With the above-described configuration, it is possible to increase a speed of diffusion of the adsorbate in the heat storage material through spraying of the adsorbate on the heat storage material.

An assembly method of an apparatus suitable for pressurized liquid transfusion is disclosed. In one step, a nozzle is to be inserted into the through hole of an elastomeric ring. Because the dimension of the nozzle is larger than the through hole, the internal wall of the elastomeric ring is tensioned and deformed so as to fit the nozzle. In one step, the elastomeric ring along with the nozzle is inserted into a receptacle. The dimension of the outer contour of the elastomeric ring needs to be decreased so as to be accommodated by the receptacle. Due to the flexibility of the elastomeric ring, it resumes at least partially to its original shape. Therefore, proper seal is created and maintained between the elastomeric ring and the nozzle such that leakage and pressure loss may be prevented. The foregoing is capable of working under high-pressured environment for prolonged use.

A spray attachment for bringing out fluid substances in the manner of a jet includes a cap with an annularly peripheral, closed skirt with a wall, on whose inner side or outer side first fastener is integrally formed. The first fastener can engage a corresponding second fastener of an outer wall or inner wall of a container neck. The skirt at a longitudinal end is closed off by a cover surface having a recess. A receiving part for receiving an insert part is arranged in the region of the recess, and includes a conical receiving surface for receiving a conical peripheral surface of the insert part. The conical receiving service and the conical peripheral surface delimit at least one through-channel for fluid substance, through which the fluid substance can be brought out.
