  • Publication number: 20180361637
    Abstract: To produce sealing plates (1) consisting of a plurality of sealing rings (3) connected by radial webs (2) by injection molding, wall-type guide elements (5) are arranged obliquely to the direction of flow in the mold channel (6) which is therefore initially largely constricted in the region of weld lines (15) formed by the convergence of the fronts of the divided plastic melt streams, said guide elements being moved out of the mold channel (6) during the further filling of same so that the strength is significantly improved in the region of the weld lines (15).

  • Publication number: 20180058278
    Abstract: An invention refers to a lubricant injector, a lubrication system and a method for providing lubricant for a piston machine. The lubricant injector is provided with a lubricant inlet conduit and an outlet opening, through which a lubricant is supplied to an inner space to be lubricated of a piston machine. The outlet opening may be selectively opened and closed by means of a needle valve, which is actuated by a magnet coil. The lubricant injector has a flow sensor suitable for determining the quantity of lubricant delivered through the outlet opening.

  • Patent number: 9702353
    Abstract: A valve plate (1) made of fiber-reinforced plastic for gas exchange valves for reciprocating piston compressors comprises at least two concentric sealing rings (3) which cooperate with corresponding sealing surfaces (4) at the valve seal (5) by way of profiled sealing surface (2) and that are connected by way of radial webs (6). In order to improve the flexibility of the valve plate (1) and the sealing behavior, the webs (6) are designed thinner along the entire radial extent thereof between the sealing rings (3) on both sides of the valve plate (1) compared to the adjacent thickness of the sealing rings (3).

  • Patent number: 9568101
    Abstract: High temperatures of the sealing medium occur in a hydraulic sealing medium barrier for sealing a piston rod of a piston compressor, and there is the risk of soil and abrasion being deposited there and interfering with the function of the seal. To prevent this, a sealing configuration (1) which is provided for circulating sealing medium through an outlet line (11) for sealing medium which is connected to the recess (10), and a circulating device (13) is provided, with which the sealing medium is circulated through the recess (10) while maintaining the pressure (poil) of the sealing medium through the inlet and the outlet line (7, 11).

  • Patent number: 9567994
    Abstract: A shutoff valve (2) which is switchable in a cycled manner for capacity regulation by temporarily shutting off the intake gas feed is designed as a multi-element ring valve, and is directly actuated by means of an electromagnet (12). The actuating forces for switching the shutoff valve (2) may be kept small via pressure compensation from the intake gas feed (3) to behind the anchor plate (9).

  • Patent number: 9476421
    Abstract: A cylinder head for a two-stage reciprocating piston compressor includes an intercooler that is designed as a cooled overflow channel between the pressure side of the first stage and the suction side of the second stage, wherein the overflow channel has a substantially slot-like cross-section, and the overflow channel is in addition divided by at least one indirectly cooled center rib so that therefrom at least two overflow channel portions and are created. The cylinder head has a cylinder head upper part and a cylinder head lower part, the cross-section of the indirectly cooled center rib is divided in its longitudinal extent thereby forming a passage gap between the overflow channels and that run on both sides, and one portion of the center rib is formed from the cylinder head upper part and the other portion of the center rib is formed from the cylinder head lower part.
