摘要： A compressor may include first and second scrolls, and an axial biasing chamber. Spiral wraps of the scrolls mesh with each other and form compression pockets including a suction-pressure compression pocket, a discharge-pressure compression pocket, and intermediate-pressure compression pockets. The axial biasing chamber may be disposed axially between the second end plate and a component. Working fluid disposed within the axial biasing chamber may axially bias the second scroll toward the first scroll. The second end plate includes outer and inner ports. The outer port is disposed radially outward relative to the inner port. The outer port may be open to a first one of the intermediate-pressure compression pockets and in selective fluid communication with the axial biasing chamber. The inner port may be open to a second one of the intermediate-pressure compression pockets and in selective fluid communication with the axial biasing chamber.

摘要： The invention relates to an assembly comprising a vacuum pump and a chamber, wherein a suction tract extends between the chamber and the vacuum pump. The vacuum pump is a liquid ring machine. According to the invention, a liquid outlet is arranged in the suction tract in order to add liquid to gas sucked in from the chamber. The invention further relates to a method for evacuating a chamber filled with vapor. According to the invention, the vapor is condensed by introducing additional liquid into the suction tract, thus by co-condensation. By supplying liquid selectively only when liquid is required for the condensation of the vapor, water is saved.

摘要： A control mechanism for a fluid displacement apparatus is disclosed. The control mechanism controls fluid communication between an intemediate pressure chamber and a suction chamber of the fluid displacement apparatus, which has a communication channel extending between the intermediate pressure chamber and the suction chamber. The mechanism includes a first valve element having a cylinder and a piston slidably disposed within the cylinder between positions corresponding to maximum and reduced displacement of the compressor. This movement defines a maximum amplitude of the compressor. The cylinder has a bottom wall seperating the cylinder chamber from the suction chamber. A hole is formed in a wall between the cylinder chamber and the intermediate pressure chamber. A distance between the bottom wall and the hole is designed to be greater than the maximum amplitude to prevent the piston from striking the bottom wall. Different shapes may be used for the hole to change the nature of the transition from maximum to reduced displacement.

摘要： The invention relates to a rotary displacement compressor having volume ratio regulation. A connection channel (8,9,10) connects the working space of the compressor to the pressure channel (5). In the channel (8,9,10) there is provided means (13) for sensing the direction of flow through the channel. The direction of flow is an indication of whether there is over or under compression. Signals from the flow direction sensing means (13) affect the position of a movable edge (29) of the outlet port (32) so that this edge (29) will move to a position where the internal compression complies with the outlet pressure. By using the direction of flow as the governing parameter for the volume ratio regulation instead of the pressure difference or the power consumption of the prime mover according to known technique, a more accurate adaption of the volume ratio to the outlet pressure is achieved.

摘要： A gas compressor of the variable volume type having a rotary plate which is rotated to move recesses therein communicating with a compression chamber of a cylinder relative to communication ports formed in a front side block fixed to the one side of the cylinder so that the volume of the compression chamber may be made variable in accordance with the fast or slow running state of the gas compressor. The rotary plate is moved rotatably by means of a self-contained and self-actuated hydraulic cylinder which is driven by oil within the compressor in response to the intake pressure of the compressor's intake chamber.
