The invention relates to an atomizer unit of a minimal quantity lubricant system (2) for a cooling and/or lubricating function of a cutting-machining process. The atomizer unit (3) has a chamber assembly (8) with an injection chamber (9) and an atomizer chamber (10), wherein the injection chamber (9) is connected to the atomizer chamber (10) by a nozzle (11), and the atomizer unit (3) has at least one first feed channel (12) for feeding a first compressed air flow (13) into the injection chamber (9), at least one second feed channel (14) for feeding a second compressed air flow (15) into the atomizer chamber (10), and an injection valve (16) for injecting a coolant and/or lubricant (4) into the first compressed air flow (13) in the injection region (17) of the injection chamber (9). The atomizer unit (3) is designed such that the first compressed air flow (13) flows from the injection chamber (9) into the atomizer chamber (10) through the nozzle (11), is atomized in the atomizer chamber by the nozzle (11), is combined with the second compressed air flow (15) in the atomizer chamber (10) in order to form a transport flow (18) for transporting the injected coolant and/or lubricant (4), and can be conducted to the machining location (7). The atomizer unit (3) has a heater (20) which heats the coolant and/or lubricant (4), the first compressed air flow (13), the second compressed air flow (15), and/or the transport flow (18).

A machine tool chip removal device including a coupling interface to couple with a rotatable spindle of a machine tool to facilitate rotation of the machine tool chip removal device about an axis at a rotational speed. The chip removal device can also include a main fluid channel with an opening to receive pressurized fluid from the machine tool. The chip removal device can further include a first fluid delivery channel and a second fluid delivery channel to direct fluid in different directions. Each fluid delivery channel can be in fluid communication with the main fluid channel. In addition, the chip removal device can include one or more valves associated with the first and second fluid delivery channels to selectively allow fluid passage from the main fluid channel to the fluid delivery channels. The one or more valves can be actuated by varying fluid pressure and/or rotational speed.

A nozzle assembly includes a body, a valve member, and a clamp member maintaining a flow director member against the body. The flow director member is sandwiched between the peripheral wall and the clamp member, and is provided with an outlet path including two distinct guidance channels extending from an upstream end and a common downstream end where is a spray hole. The outlet path creates impingement of the two flow streams flowing in the two channels before entering the spray hole.

Disclosed are systems, devices, methods and kits, for adapting a standard toilet that works with an existing water supply and/or plumbing to provide the functionality of a bidet. Additionally, disclosed are solution delivery systems operable to deliver a soap-free, zero residue cleaning agent. Also disclosed are fluid delivery devices that provides improved control of a stream of fluid from a bidet system that targets the anatomical area of interest.

A dust suppression system has one or more fluid dischargers configured to discharge a fluid capable of suppressing generation of dust to a work area of a building by remote operation. The fluid discharger includes a discharge nozzle configured to discharge the fluid; a first swivel joint structure including a first rotating-side body connected to and supporting the discharge nozzle and a first fixed-side body rotatably supporting the first rotating-side body; a first electric linear motion mechanism including a first support part and a first movable part supported by the first support part in a linearly movable manner; and a first rotation mechanism configured to convert linear motion of the first movable part into rotational motion to rotationally displace the first rotating-side body. The dust suppression system can further reduce power consumption as well as can accurately discharge a fluid from a fluid discharger to a predetermined work area.

A spray bar injector including a spray bar defining a longitudinal axis and including a fluid inlet and a plurality of spray outlet orifices spaced apart longitudinally in a direction along the longitudinal axis. A check or spray valve is operatively connected to each spray outlet orifice. A master valve is in fluid communication with the fluid inlet, operatively connected to divert flow from the fluid inlet into a first passage and block flow into a second passage in a first position to open the check valves and issue a spray from the spray outlet orifices, and to divert flow from the fluid inlet into the second passage and block flow into the first passage in a second position to close the check valves and block issue of spray from the spray outlet orifices.

A jet valve has a medium passage that leads to a discharge opening and that is closable by a sealing element that can be set against a seal seat. The seal seat has a sealing surface in the form of an annular strip. The jet valve has a high service life and is suitable for metering very small quantities.

An applicator system for applying a material to a substrate is disclosed, the applicator system having a nozzle assembly (28) that includes a nozzle having a nozzle head (108). The nozzle assembly (28) also includes a baffle plate (101) including a cutout (144) that extends through the baffle plate (101), where the baffle plate (101) is received by the nozzle head (108) such that the nozzle head (108) and the baffle plate (101) define a cavity. The nozzle assembly (28) further includes a cover plate (102) attached to the nozzle head (108) such that the cover plate (102) secures the baffle plate (101) within the nozzle head (128), where an outlet passage is defined between the baffle plate (101) and the cover plate (102), the outlet passage being fluidly connected to the cavity through the cutout (144) of the baffle plate (101).
