<p>A pressure valve for a compressor, in particular a hermetically encapsulated small-size refrigerating machine, comprising the following elements: a valve plate (33), a cylinder cover (40)comprising a substantially quadrangular base plate with cylinder walls formed thereon, with the valve plate (33) and the cylinder cover (40) being mutually connected by means of fastening elements, and with a seal (58) arranged in between and a valve spring (23) arranged in the volume enclosed by the valve plate (33) and the cylinder lid (40), a substantially U-shaped holding-down element (21) with pins and legs taking the squaring and, optionally, a damper element (27), with the valve spring, the damper element and the holding-down element being arranged in this sequence above the valve seat. In order to decisively reduce the amount of production work and to enable a pre-assembly of the holding-down element including the valve spring and the damper element with the valve plate it is provided that the valve plate (33) is provided with a plan arrangement and comprises bores (36), and pins (15, 16a, 16b) which correspond with the bores (36) are arranged on the holding-down element (21), with the distance of the pins (15, 16a, 16b) from one another being slightly different from the distance of the bores (36) from one another, so that during the insertion into the valve plate (33) an initial tensioning of the holding-down element occurs which ensures the holding of the elements on the valve plate.</p> |
