Abstract
Method for the stepless regulation of the delivery of a suction valve of the plate-type of construction, comprising a valve plate which is actuated by an electromagnet arranged in a valve catcher, wherein the electromagnet is so controlled that, in a first control phase (11a), the valve plate (3) firmly contacts the valve catcher (6), or a damper plate (4) arranged between the valve catcher (6) and the valve plate (3) and is blocked, and that, in a second control phase, the electromagnet (9) is controlled by a decaying alternating current, in order to demagnetise the valve plate (3), so that the valve plate is released.
Claims21
A method for the stepless regulation of delivery of a suction valve of a plate-type of construction comprising a valve plate, an electromagnet arranged in a valve catcher and a damper plate arranged between the valve catcher and the valve plate, the method comprising:
- actuating the valve plate with the electromagnet;
- controlling the electromagnet in a first control phase such that the valve plate firmly contacts one of the valve catcher or the damper plate such that the valve plate is blocked;
- and
- controlling the electromagnet in a second control phase by a decaying alternating current such that the valve plate is at least partly demagnetized thus releasing the valve plate.
An apparatus for the actuation of a valve plate of a suction valve of plate-type construction, the apparatus comprising a valve catcher and an electronic control device, wherein the valve catcher is formed of a ring body that has a ring groove extending in the circumferential direction and also a magnet coil arranged in the ring groove such that the ring body forms a yoke of a ring body magnet of an electromagnet, wherein the magnet coil is connected to the control device in order to attract the valve plate forming an armature of the electromagnet, and wherein the electromagnet is controlled during, a control phase by a decaying alternating current such that the valve plate is at least partly demagnetized.
A suction valve of plate-type construction comprising a valve seat, a valve plate with valve springs, and an apparatus comprising a valve catcher and an electronic control device, wherein the valve catcher is formed of a ring body that has a ring groove extending in the circumferential direction and also a magnet coil arranged in the ring groove such that the ring body forms a yoke of a ring body magnet of an electromagnet, and wherein the magnet coil is connected to the control device in order to attract the valve plate forming the armature of the electromagnet;
- and
- wherein the valve plate and the valve seat are directly placed on top of one another;
- wherein the electromagnet is controlled during a control phase by a decaying alternating current such that the valve plate is at least partly demagnetized.
A piston compressor including an apparatus comprising a valve catcher, a valve plate and an electronic control device, wherein the valve catcher is formed of a ring body that has a ring groove extending in the circumferential direction and also a magnet coil arranged in the ring groove such that the ring body forms a yoke of a ring body magnet of an electromagnet, and wherein the magnet coil is connected to the control device in order to attract the valve plate forming the armature of the electromagnet.
A method for the stepless regulation of delivery of a suction valve of a plate-type of construction comprising a valve plate and an electromagnet arranged in a valve catcher, the method comprising:
- actuating the valve plate with the electromagnet;
- controlling the electromagnet in a first control phase such that the valve plate firmly contacts the valve catcher such that the valve plate is blocked;
- and
- controlling the electromagnet in a second control phase by a decaying alternating current such that the valve plate is at least partly demagnetized thus releasing the valve plate.
