The invention relates to a dishwasher (1), in particular a household dishwasher, comprising a washing container (2) for accommodating wash items to be cleaned, wherein the wash items can be exposed to a washing liquor liquid (S) by means of at least one first spraying device (6) and/or at least one further introducing unit (7) and wherein a switchable inflow retarder is provided, which leaves open all inflow lines (18, 19) for the inflow of washing liquor liquid (S) to the first spraying device (6) and to each further introducing unit (7) in a passage position and completely or partially blocks at least one inflow line (19) to the at least one further introducing unit (7) in a closed position, wherein the inflow retarder comprises at least one closing body (13) that is arranged in the flow of washing liquor liquid (S) and that can be controlled without contact and that can be driven, solely by means of force introduced without contact, at least between the passage position, which releases all inflow lines (18; 19) to the first spraying device (6) and to the further introducing unit(s) (7), and the blocking closed position, in which the at least one inflow line (19) to the at least one further introducing unit (7) is blocked.
摘要:
Device for separating oil from the de-aeration of an oil reservoir, which device comprises a line (3) for the de-aeration which is connected to the above-mentioned oil reservoir (1) with one far end and in which is provided a suction pump (4) for sucking in air, and whereby the other far end of the above-mentioned line (3) is connected to a filter (7) which is provided in a chamber (8) which is connected to the above-mentioned oil reservoir (1) by means of a return line (9), and which chamber (8) is provided with an outlet (10) to the environment, characterised in that a non-return valve (12) is provided in a the above-mentioned return line (9) which lets an air flow pass from the oil reservoir (1) to the chamber (8), and which prevents an air flow in the opposite direction, and whereby this non-return valve is provided with a small flow-back opening (16) which allows the oil which has been separated in the chamber (8) by the filter (7) to flow back to the oil reservoir (1).
摘要:
Eine Entlüftungsvorrichtung hat einen Rahmen (12) aus einer ersten Materialkomponente und ein Rückschlagklappenelement (14) aus einer zweiten Materialkomponente, wobei die erste Materialkomponente härter ist als die zweite Materialkomponente. Das Rückschlagklappenelement (14) weist eine bewegliche Rückschlagklappe (18) auf, die so angeordnet ist, daß sie ausschließlich am Rückschlagklappenelement (14) anliegt oder die Entlüftungsvorrichtung (10) ist an einem Fahrzeugteil (28) anbringbar, wobei der Teil der Entlüftungsvorrichtung (10), der am Fahrzeugteil (28) angreift, Teil des Rückschlagklappenelementes (14) ist.
摘要:
A valve assembly (10) may include a valve body (16) having a main body portion (20) and a mounting portion (22). The main body portion (20) may include a perimeter, a first side (26) and a second side (28). The first side (26) may define a sealing portion extending proximate to and substantially around the perimeter. The sealing portion may mate with a valve seat (40). The second side (28) of the main body portion may be convexly curved. The valve body (16) may disposed within a flow path define by one or more conduits (12,14). The flow path may have at least a portion with a generally circular cross section having a radius. The first side (26) may mate with a valve seat (40). The main body portion (20) may be moveable within the flow path relative to the valve seat (40) between an open position and a closed position.
摘要:
The device (1) for providing anti-reflux has a valve element (9) formed from a sheet-shaped material blank. The valve element includes a connecting portion and a flap portion. Retaining means (10a, 10b) for retaining the valve element are integral with the device. The connecting portion includes engagement means formed integrally with the valve element for engagement with the retaining means, the valve element projecting a coherent plane.
摘要:
An inflation valve assembly (110), for a dunnage or cargo air bag, comprises an annular flange member (112) which is adapted to be heat-sealed to an interior surface portion of one of the plies of the inflatable bladder of the air bag, and an externally threaded nipple portion (116) for fluidic connection to a source of pressurized fluid for inflating the bladder of the dunnage or cargo air bag. The inflation valve assembly also has a substantially C-shaped upstanding ring member (118) integrally disposed upon the upper surface portion (120) of the annular flange member (112), and a substantially planar, disc-type flapper valve member (122), having a substantially circular configuration, has an end portion which is adapted to be fixedly secured upon an arcuate portion (126) of the upper surface portion (120) of the annular flange member by means of a fixation bar (128) which extends along a chordal extent of the annular flange member. Opposite end portions of the fixation bar (128) project radially inwardly toward each other so as to effectively define a pair of oppositely disposed detents (134) for maintaining the flapper valve (122) member in its OPENED state. Accordingly, the height dimension or depth profile of the new and improved inflation valve assembly of the present invention is able to be substantially reduced so as to enable the inflation valve assembly to readily facilitate the sealing of the inflatable bladder during the fabrication thereof.
摘要:
The invention relates to a valve, especially an air entry and air exit ventilation valve for the passenger compartment of a motor vehicle, comprising a housing (1) and at least one closing flap (2) which rests against transversal elements (5) of the housing (1) when in an inoperative position and which is connected to the housing (1) over a supporting area. According to the invention, the housing (1) and the closing flap (2) are produced in a two-component injection molding method, whereby the housing (1) is comprised of a hard material component, and the closing flap (2) is comprised of a material component that is softer than said hard material component. The supporting area of the closing flap (2) and/or of the area of the housing (1) interacting therewith comprise(s) at least one retaining profile which engages inside at least one recess.
摘要:
Es wird ein Rückschlagventil vorgeschlagen, das ein bewegliches Verschlußglied aufweist, das zur Steuerung des Fluiddurchganges durch einen in einem Gehäuse verlaufenden Strömungskanal (8) mit einem Ventilsitz (43) zusammenarbeiten kann. Das Verschlußglied ist als Verschlußplatte (44) ausgebildet, die in der Durchgangsöffnung eines Halteringes (48) angeordnet ist, mit dem sie unter Bildung einer Baueinheit an einer Stelle ihres Umfangsrandes über einen flexiblen Biegebereich in einstückiger schwenkbeweglicher Verbindung steht. Der Haltering (48) ist in einer den Strömungskanal (8) umgebenden Betriebsstellung derart gehäusefest fixierbar, daß die Verschlußplatte (44) dem Ventilsitz (43) gegenüberliegt.
