Patent number: 7316291Abstract: The invention concerns a suction muffler for a hermetic refrigerant compressor with a housing having an inlet and an outlet and limiting at least one muffling chamber, and a gas supply channel located in the muffling chamber between the inlet and the outlet. It is endeavoured to prevent too much oil from remaining in the refrigerant gas flow. For this purpose, the gas supply channel forms a throttling path and ends in the muffling chamber, and that in the area of the inlet of the gas supply channel an oil extraction opening is located, which ends in the muffling chamber.Type: GrantFiled: May 13, 2004Date of Patent: January 8, 2008Assignee: Danfoss Compressors GmbHInventors: Jan Thomsen, Preben Bjerre, Christian Svendsen, Morten Svendsen, Klaus Reinwand

Publication number: 20070196217Abstract: The invention concerns a cylinder head arrangement for a piston compressor, with a cylinder block, in which a compression chamber is formed, which is delimited on one side by a valve plate that is clamped between the cylinder block and a cylinder head cover. In order to provide a cylinder head arrangement that has a high degree of tightness and can be manufactured in a cost-effective manner, the valve plate (6) has on at least one side at least one bead (40) projecting from the valve plate surface (21) concerned.Type: ApplicationFiled: February 16, 2007Publication date: August 23, 2007Applicant: Danfoss Compressors GmbHInventors: Brian Holm Andersen, Morten Svendsen, Klaus Reinwand, Ole Jons, Jorg Fritsche, Preben Bjerre

Publication number: 20070041856Abstract: The invention concerns a linear compressor (1) with a piston (16) reciprocating in a cylinder (8), a linear motor acting upon the piston (16) and a resonance spring arrangement (5) connected with the piston (16). It is endeavoured to reliably avoid damaging the compressor during operation. For this purpose, the resonance spring arrangement (5) has a fixed stop (48) allocated to the upper dead point of the piston (16).Type: ApplicationFiled: August 9, 2006Publication date: February 22, 2007Applicant: Danfoss Compressors GmbHInventors: Poul Hansen, Klaus Reinwand, Kaja Lenz, Jan Thomsen, Preben Bjerre, Frank Iversen, Marten Nommensen

Publication number: 20070040456Abstract: The invention concerns a linear compressor (1), particularly a refrigerant compressor, with a linear motor (4), which comprises an outer stator (18), an inner stator (20) and an armature (22) located in a gap (21) between outer stator (18) and inner stator (20), and a compression unit (3), which has a cylinder (8) and a piston (16) reciprocating in the cylinder (8) and being connected to the armature (22). It is endeavoured to simplify the design of the compressor. For this purpose, the inner stator (20) and the outer stator (18) are held and positioned in relation to each other at both axial ends by means of motor covers (29).Type: ApplicationFiled: August 9, 2006Publication date: February 22, 2007Applicant: Danfoss Compressors GmbHInventors: Poul Hansen, Klaus Reinwand, Kaja Lenz, Frank Iversen

Publication number: 20070041854Abstract: The invention concerns a linear compressor (1), particularly a refrigerant compressor, with a compression unit (3) having a cylinder (8) and a piston (16) reciprocating in the cylinder (8), and a linear motor (4) having an outer stator (18), an inner stator (20) and an armature (22) located in a gap (21) formed between the outer stator (18) and the inner stator (20), the armature (22) being connected to the piston (16) via a piston rod (28). It is endeavoured to design such a linear compressor in a simple manner with the smallest possible dimensions. For this purpose, it is ensured that the armature (22) is connected to the piston rod (28) inside the axial length of the inner stator (20).Type: ApplicationFiled: August 9, 2006Publication date: February 22, 2007Applicant: Danfoss Compressors GmbHInventors: Poul Hansen, Klaus Reinwand, Jan Thomsen

Publication number: 20070041853Abstract: The invention concerns a linear compressor (1), particularly a refrigerant compressor, with a first component group comprising a stator (18, 20) of a linear motor (4) and a cylinder (8, 10), a second component group comprising a reciprocating piston (16) and an armature (22) of the linear motor (4) as well as a piston rod (28) connecting the armature (22) to the piston (16), an oil sump in a housing (2) and an oil pump (38), the second component group being movable in relation to the first component group. It is endeavoured to provide a simple design ensuring a lubrication of the linear compressor. For this purpose, the oil pump (38) has a pump housing (40) that is permanently connected to the piston rod (28), the pump housing (40) immersing with at least one suction opening (43; 43a, 43b) into the oil sump (41), the oil pump (38) supplying oil to the inside of the piston rod (28).Type: ApplicationFiled: August 9, 2006Publication date: February 22, 2007Applicant: Danfoss Compressors GmbHInventors: Poul Hansen, Klaus Reinwand, Jan Thomsen, Frank Iversen

Patent number: 6688432Abstract: The invention concerns a piston compressor, particularly a hermetically enclosed piston compressor, with a housing, in which a motor is arranged, the motor having a crankshaft with a vertically standing crank pin that has in its upper front side an opening, which is connected with an oil supply arrangement. It is endeavored to reduce an external oil circulation. For this purpose, the opening is provided with a limiting arrangement, which limits an axially directed movement of lubricating oil from the opening to a predetermined area.Type: GrantFiled: January 28, 2002Date of Patent: February 10, 2004Assignee: Danfoss Compressors GmbHInventors: Jens Erik Nissen, Christian Svendsen, Frank Holm Iversen, Klaus Reinwand, Preben Bjerre
