Patent number: 8678794Abstract: The invention concerns a refrigerant compressor arrangement (1) with a housing (2, 3) comprising a suction opening (5), a compressor (15), which is arranged in the housing (2, 3), and is connected to the suction opening (5), and a suction connection (20) that is fixed at the housing (2, 3), and comprises a housing section (21) and a tube section (22), the housing section (21) being connected to the suction opening (5) and the diameter of the tube section (22) being different from the diameter of the housing section (21). With such a refrigerant compressor arrangement, it is endeavoured to keep the dimensions small. For this purpose, in the longitudinal direction of the suction connection (20) the housing section (21) and the tube section (22) overlap each other and are connected to each other by a corrugated area (23) with at least one radial corrugation.Type: GrantFiled: January 16, 2009Date of Patent: March 25, 2014Assignee: Secop GmbHInventors: Frank Holm Iversen, Marten Nommensen, Heinz Otto Lassen, Ekkehard Handke, Dirk Sommer

Patent number: 8596187Abstract: The invention relates to a method of calibrating a connecting rod arrangement comprising a crankshaft eye and a connecting rod eye. In order to achieve the best possible parallelism between the connecting rod eye and the crankshaft eye a controlled energy input occurs in at least one predefined surface area of the connecting rod, so that outside a neutral axis a local structural change and thus a tension in the connecting rod occurs.Type: GrantFiled: January 21, 2010Date of Patent: December 3, 2013Assignee: Secop GmbHInventors: Marten Nommensen, Heinz-Otto Lassen

Patent number: 8356549Abstract: The invention concerns a method of mounting a cylinder arrangement of a hermetically enclosed refrigerant compressor arrangement in a carrier arrangement (14, 15), in which the cylinder arrangement is inserted in the carrier arrangement (14, 15), aligned in relation to a crank shaft (5) and connected to the carrier arrangement (14, 15). It is endeavored to ensure a good efficiency of the refrigerant compressor arrangement. For this purpose the carrier arrangement is deformed, before inserting the cylinder arrangement, by means of a calibration cylinder (40), until the calibration cylinder (40) has a predetermined alignment, after which the calibration cylinder (40) is removed and replaced by the cylinder arrangement in the carrier arrangement (14, 15).Type: GrantFiled: May 15, 2009Date of Patent: January 22, 2013Assignee: Secop GmbHInventors: Frank Holm Iversen, Marten Nommensen, Ekkehard Handke, Norbert Stöcken

Patent number: 8162624Abstract: A refrigerant compressor (1) includes a cylinder block (4), in which a cylinder (14) is arranged, and a cylinder head (16), which covers the front side of the cylinder (14) and is connected to the cylinder block (4) by a plurality of threaded bolts (18, 19). It is endeavored to achieve a good performance with a small mass of the refrigerant compressor. For this purpose, it is ensured that at least two threaded bolts (18) extend through the cylinder block (4) and are screwed into a common mating thread element (23) at the end projecting from the cylinder block (4).Type: GrantFiled: October 29, 2008Date of Patent: April 24, 2012Assignee: Secop GmbHInventors: Jesper Valbjoern, Anders Jakob Madsen, Kristoffer Riemann Hansen

Patent number: 8125118Abstract: The invention concerns a winding head isolation element (1) with a body (2, 3) having a first longitudinal side (5), a second longitudinal side (6), a first transversal side (7) and a second transversal side (8), and a tongue portion (9) projecting from the first longitudinal side (5), the body (2, 3) and the tongue portion (9) being made of a flat material. It is endeavored to keep the efforts and costs for the mounting of the isolation element on a winding head small. For this purpose, the body (2, 3) is deformable around an axis (4) extending transversely to the tongue portion (9) and has at least one opening (21, 22) extending transversely to the tongue portion (9), said tongue portion (9) being adapted for insertion through the opening.Type: GrantFiled: September 12, 2008Date of Patent: February 28, 2012Assignee: Secop GmbHInventor: Iwer Nissen

Patent number: 8062005Abstract: The invention concerns a linear compressor, particularly a refrigerant compressor, with a housing (2, 2?) and a compression unit, which comprises a compressor with a piston and a cylinder as well as a linear motor driving the piston in relation to the cylinder along a movement axis, the compression unit (30) being connected to the housing (2) via a spring arrangement (7). It is endeavoured to provide a space saving support of the compression unit (30) in the housing that enables good vibration suppression. For this purpose, the spring arrangement comprises a spring (6, 7), which is curved in the circumferential direction in relation to the movement axis (50), said spring surrounding the compression unit (3-5) on at least a share of its circumference.Type: GrantFiled: August 9, 2006Date of Patent: November 22, 2011Assignee: Secop GmbHInventors: Poul Erik Hansen, Jan Thomsen, Frank Holm Iversen

Patent number: 8063597Abstract: An electric circuit for supplying power to a DC application is disclosed. The electric circuit comprises a DC power source (1) connectable to an alternator charging circuit (2), an FET (T7), and a capacitor (8) connected across the gate terminal and the source terminal of the FET (T7). The drain terminal of the FET (T7) is connected to a negative terminal of the DC source (1). The FET (T7) protects the circuit against accidental connection of the alternator charging circuit (2) to the DC power source (1) with reversed polarity, by opening a switch (6) of the FET (T7) when this occurs. The capacitor (8) protects the FET (T7) from being pushed into avalanche in case a load-dump transient occurs. This is because the capacitor (8) in this case will charge and discharge, thereby introducing a time delay before the switch (6) is opened. Protection against load-dump transients is thereby obtained by means of a small component with low energy dissipation.Type: GrantFiled: September 18, 2007Date of Patent: November 22, 2011Assignee: Secop GmbHInventor: Rune Thomsen
