摘要： A refrigeration cycle apparatus includes a first flow switch valve including first to fourth ports, a second flow switch valve and a third flow switch valve each including fifth to seventh ports, a compressor, a discharge pipe connecting a discharge port of the compressor and the first port, a first high pressure pipe connecting between the discharge pipe and the fifth ports, a bypass expansion valve provided at a part of the first high pressure pipe, the part extending, a first outdoor heat exchanger connected to the seventh port of the second flow switch valve, a second outdoor heat exchanger connected to the seventh port of the third flow switch valve, and a controller. The controller is configured to perform a differential pressure ensuring process, when switching the second flow switch valve or the third flow switch valve. In the differential pressure ensuring process, the controller is configured to set operation frequency of the compressor to a first frequency and set opening degree of the bypass expansion valve to a first degree if a first condition is not met, and set the operation frequency of the compressor to a second frequency which is higher than the first frequency or set the opening degree of the bypass expansion valve to a second degree which is larger than the first degree if the first condition is met.

摘要： A valve member (30) of an electric-operated valve includes a control portion (35) and a movement restriction portion (37). The control portion (35) includes a control surface (36) that is an annular tapered surface facing outward. A valve port (15) is closed when the control surface (36) is in contact with an upper end (16a) of the valve port (15). The movement restriction portion (37) includes a movement restriction surface (38) that is an annular tapered surface facing outward. Movement of the control portion (35) toward the valve port (15) is restricted when the movement restriction surface (38) is in contact with an outer peripheral edge (18a) of a valve seat (18) of a valve body (10). The movement restriction surface (38) comes into contact with the outer peripheral edge (18a) when the control surface (36) is in contact with the upper end (16a).

摘要： A control valve (1) comprising:
a body (10) including an inlet port (18) through which fluid is introduced, an outlet port (20) through which the fluid is delivered, a valve hole (30, 530) through which the inlet port (18) and the outlet port (20) communicate with each other, and a valve seat (32) located in the valve hole (30, 530);
a valve element (40, 540) that touches and leave the valve seat (32), in particular from a downstream side, to close and open a valve section; a spring (58) that biases the valve element (40, 540) in a valve closing direction; and
an actuator (8) that drives the valve element (40, 540) in opening and closing directions of the valve section, wherein
a rubber (162) is provided on at least one of a face of the valve element (40, 540) and a face of the valve seat (32, 532) that come in contact with each other.

摘要： Provided is a system for controlling a flow of a fluid into a reaction chamber of a machine and a corresponding method. The system comprises a Venturi tube through which the fluid is to be fed into the reaction chamber and a conical element, wherein a size of a cross-sectional area of a constriction formed by the Venturi tube can be adapted by positioning the conical element relative to the constriction. The system further comprises an actuator which is configured to position the conical element, wherein the actuator is controlled by a controller that is configured to map a target power output of the machine onto a target value for the size of the cross-sectional area of the constriction.

摘要： The present invention relates to an expansion valve, in particular for a heating and/or cooling application, comprising a movable plug (1) and a valve seat (2), wherein the distance between the plug and the valve seat defines a valve opening. The variable valve opening defines and limits a fluid flow rate through the valve, thereby ensuring a desired pressure drop across the expansion valve.
