Abstract: For a refrigerant compressor, a flexible connection element is provided which connects an end segment of a suction connection piece, which end segment protrudes into the interior of a housing, to a suction sound damper, in particular to a suction opening of the suction sound damper. The end segment itself thereby serves for fastening the flexible connection element onto the end segment and/or the inner wall of the housing.

Abstract: A cylinder head cover for a coolant compressor, wherein the cylinder head cover is attachable to a cylinder head arrangement in order to form a hollow space for receiving a coolant compressed by the piston, wherein the cylinder head arrangement comprises a valve plate attached to the cylinder housing and having an outlet opening and an outlet valve, which closes the outlet opening in cycles and consists of a valve spring and a stop plate for delimiting an opening movement of the valve spring. In order to achieve a cost-efficient production and installation of the cylinder head cover while assuring a secure support of the stop plate, it is provided that the cylinder head cover can comprise at least two contact surfaces for supporting stop plates of different outlet valves in order to adjust different opening positions of the valve springs of the different outlet valves.

Abstract: Cylinder head cover (8) for a coolant compressor, wherein the cylinder head cover (8) is attachable to the cylinder head arrangement (21) in order to form a hollow space for receiving a coolant compressed by the piston, wherein the cylinder head arrangement (21) comprises a valve plate (9) attached to the cylinder housing and having an outlet opening (11) and an outlet valve (6,7), which closes the outlet opening (11) in cycles and consists of a valve spring (10) and a stop plate (6a,7a) for delimiting an opening movement of the valve spring (10). In order to achieve a cost-efficient production and installation of the cylinder head cover (8) while assuring a secure support of the stop plate (6a,7a), it is provided according to the invention that the cylinder head cover (8) comprises at least two contact surfaces (12,13) for supporting stop plates (6a,7a) of different outlet valves (6,7) in order to adjust different opening positions of the valve springs (10) of the different outlet valves (6,7).

Abstract: An ATR objective (1) for an IR microscope has a Cassegrain objective (2), an ATR crystal (7), a holding bar (8) to one end of which on the side of the sample, the ATR crystal (7) is mounted, a holding element (10), thin struts (9) which rigidly connect the holding bar (8) to the holding element (10) and intersect an optical path of the ATR objective (1) entering or exiting the Cassegrain objective (2) in such a fashion that they shade less than 10% of the beam cross-section of the optical path, and a motor drive (12) for axial movement of the holding element (10) relative to the sample position (3). The automated ATR objective thereby enables simple adjustment of operating modes and different contact pressures of the ATR crystal with respect to a sample (19).

Abstract: ATR (attenuated total reflection) objective (1) for an IR (infrared) microscope, comprising a Cassegrain objective (2) which focuses on a sample position (3) and the two mirrors (2a,2b) of which each have a central bore (5a, 5b), an ATR crystal (7), a holding bar (8) which is guided through the two central bores (5a, 5b) and to one end of which on the side of the sample, the ATR crystal (7) is mounted, a holding element (10) which is disposed in the area or beyond the side of the Cassegrain objective (2) facing away from the sample, thin struts (9) which rigidly connect the holding bar (8) to the holding element (10) and intersect an optical path of the ATR objective (1) entering or exiting the Cassegrain objective (2) in such a fashion that they shade less than 10% of the beam cross-section of the optical path, and a motor drive (12) for axial movement of the holding element (10) relative to the sample position (3).

Abstract: A connection device for establishing a coupling appropriate for transmission of an electrical or optical signal between a first connector piece and a second connector piece includes a socket, into which the first connector piece, which is designed as a plug, can be plugged detachable in one plug direction, and a base on which the second connector part is mounted or is mountable. The socket is adjustable with respect to the base transverse to the plug direction between a function position, in which the socket aligns with the second connector piece and in which the first connector piece can be plugged into the socket and is coupled with the second connector piece to transmit signals when plugged in, and a cleaning position, in which the socket is displaced to the side of the second connector piece and in which the second connector piece is exposed for cleaning.
