摘要： A grease leakage preventing structure is provided for a gear reducer of a dynamoelectric machine with a gear reducer, which is capable of preventing, if soft grease with high consistency is employed in a gear reducer driven at a high speed for high output power, leakage of grease from the reducer toward the dynamoelectric machine, by covering an output shaft of the dynamoelectric machine with a grease blocking member. In a grease leakage preventing structure for a gear reducer of a dynamoelectric machine with the gear reducer, in which gear teeth are provided in a leading edge portion of the output shaft of the dynamoelectric machine, the leading edge portion of the dynamoelectric machine output shaft is introduced into a case of the gear reducer via an input port of the gear reducer, and the dynamoelectric machine output shaft with the gear teeth is engaged with a gear arranged inside the case of the gear reducer, the grease leakage preventing structure is provided with a grease blocking member (3A, 3B, 3C, 3D) provided on a terminal end of an engagement portion (16b) of the dynamoelectric machine output shaft (14A) and is configured to inhibit inflow of grease into the dynamoelectric machine, and in this structure, the grease blocking member (3A, 3B, 3C, 3D) is provided with a wall surface portion (3Aa, 3Ba, 3Ca, 3Da) formed in a direction perpendicular to the gear teeth (16) provided in the leading edge portion of the dynamoelectric machine output shaft (14A).

摘要： A method and an ejection device are provided for discharging contaminants (CNT) out of a seal chamber (28) of a rotating-fluid machine driving a main flow (MFF) of contaminated fluid. The ejection device incorporates an obstacle (46) for arresting a portion of the flow in the seal chamber (28) to stagnation pressure, whereby a zone of fluid at stagnation pressure (ZPS) is created. A discharge passage (48) is disposed in the seal chamber (28) adjacent to a region of concentration of contaminants (CNT) and in the zone of stagnation pressure (ZPS) created by the obstacle (46), whereby contaminants are pumped out via the discharge passage into the main driven flow (MFF). The discharge passage (48) is disposed upstream of the obstacle (46) and provides fluid communication between the seal chamber (28) and a process side of the machine. The method and the ejection device are operative with a machine driving fluid in clockwise direction (CW), in counterclockwise direction (CCW), and in both clockwise and counterclockwise direction.

摘要： Assembly comprising a first hydraulic pump (10) which serves for circulating a pressure medium. In addition to the first hydraulic pump (10), a further second hydraulic pump (20) is provided which can convey pressure medium from a tank (56) as needed, and is additionally used for circulating pressure medium. The hydraulic pumps (10, 20) are connected to each other on the output side. A hydraulic accumulator (34) is additionally provided on the output side. The piston (38) of this accumulator is coupled to a control valve (50) in such a way that beginning at a determined system pressure in the hydraulic accumulator (34) this valve opens a connection between the input sides of the hydraulic pumps (10, 20). If the system pressure drops below the predetermined value, the control valve (50) closes the pressure medium connection.
