    Abstract: A powder feeding device, in particular for coating powder, is disclosed. The powder feeding device includes a dense phase powder pump which has at least one conveying chamber with a powder inlet valve and a powder outlet valve. Furthermore, a control device is provided for selectively operating the dense phase powder pump in a powder conveying more or a flushing operating mode. The powder inlet valve and the powder outlet valve of the dense phase powder pump are configured in each case as a pneumatically actuable compression valve which can be closed when an actuating pressure is applied. The control device is configured to set the pressure value of the actuating pressure which is selected for closing the powder inlet valve and/or powder outlet valve depending on the respective operating mode of the dense phase powder pump and/or depending on a pressure which prevails in the conveying chamber.

    Abstract: A flow control valve includes a valve body, a control member and a cover. The valve body has a receiving space, a resting face, a stepped face, a positioning groove and a plurality of water outlet holes. The control member is provided with an elastic portion, a sealing portion and an abutting face. When a flow pressure of the fluid is under a normal condition, the elastic portion of the control member is contracted inward, so that the abutting face of the control member is disposed at an open state. When the flow pressure of the fluid is under an abnormal condition, the elastic portion is expanded outward and abuts the stepped face of the valve body, so that the abutting face of the control member abuts the resting face of the valve body, to seal the water outlet holes of the valve body.

    Abstract: A jet regulator (1), having a perforated plate (5) arranged therein with throughflow holes (6) extending through the perforated plate for dividing the water flowing therethrough, including a central, non-perforated impingement surface (14) on the perforated plate (5), which non-perforated impingement surface is surrounded by a first annular wall (15), which has passage openings (16) that are oriented in a radial direction and extend through the first annular wall, wherein a respective throughflow hole (6), which extends through the perforated plate (5) and is connected to the respective passage opening (16), is provided on the side of each passage opening (16) arranged in the impingement surface plane. The annular wall (15) is surrounded by an annular ring chamber (29) on the outer circumferential side. A flow regulator (30) or a throttling device (300) is provided in front of the impingement surface (14) in the flow direction of the water, whereby the water consumption is restricted and/or the water flow rate becomes largely independent of the particular water pressure. Furthermore, a second annular wall (33), which has a smaller diameter than the first annular wall and is arranged at a distance from the first annular wall, is provided coaxially and concentrically to the first annular wall (15), which second annular wall has radial passage openings (34) arranged at a distance above the impingement surface (14), through which radial passage openings the water has access to the first annular wall (15) and to the passage openings (16) of the first annular wall and thus to the throughflow holes (6). Through this combination, the water flow rate through the jet regulator becomes practically independent of the water pressure upstream of the jet regulator (1).

    Abstract: The present invention relates to a powder feeding device (100), in particular for coating powder. The powder feeding device (100) comprises a dense phase powder pump (1) which has at least one conveying chamber (4) with a powder inlet valve (7) and a powder outlet valve (8). Furthermore, a control device (90) is provided for selectively operating the dense phase powder pump (1) in a powder conveying operating mode or a flushing operating mode. The powder inlet valve (7) and the powder outlet valve (8) of the dense phase powder pump (1) are configured in each case as a pneumatically actuable compression valve which can be closed when an actuating pressure is applied. It is provided according to the invention that the control device (90) is configured to set the pressure value of the actuating pressure which is selected for closing the powder inlet valve (7) and/or powder outlet valve (8) preferably automatically and more preferably selectively automatically depending on the respective operating mode of the dense phase powder pump (1) and/or depending on a pressure which prevails in the conveying chamber (4).

    Abstract: A method of controlling a regulator with a pilot device includes periodically detecting an outlet pressure at an outlet of the regulator with a feedback pressure sensor. The method also includes comparing each detected outlet pressure with a set-point control pressure. Additionally, the method includes opening an exhaust valve when a detected outlet pressure is greater than the set-point control pressure so that a loading gas, which is applied to a top surface of a diaphragm of the regulator, exhausts out through the exhaust valve to reduce loading on the diaphragm. The method further includes sensing a loading pressure in the outlet port with a loading pressure sensor after opening the exhaust valve and comparing the loading pressure to a predetermined minimum threshold pressure. When the loading pressure is equal to or less than the predetermined minimum threshold value, the method includes closing the exhaust valve.
