Abstract: A valve has a valve housing which is connected to an electronics unit. The electronics unit has an electronics unit housing which has an aperture in order to establish electrical contacting with an actuator of the valve. A portion of the actuator may protrude into the aperture. Here, play is provided between the aperture and the portion of the actuator.

Abstract: A displacement transducer for a valve in a housing includes a cylindrical displacement transducer core, a coil, a coil housing, and a compensation element. The coil is positioned in the coil housing, and radially encloses the core. The coil housing has a first side supported by the housing, and a supporting face positioned between the first side and an axial end side of the coil housing facing away from the valve such that a length change of the coil is not limited in an axial direction facing away from the valve. The housing is axially supported on the compensation element via the supporting face. A side of the compensation element facing away from the valve is supported on one or more of (i) an adjustable cover, (ii) a standard component of a supporting chain of the core, and (iii) a component formed from a material with a suitable coefficient of thermal expansion.

Abstract: An actuating solenoid and a non-stick disk by means of which adhesion of an armature of an actuating solenoid to a pole core can be prevented. The non-stick disk is provided with at least one oil channel through which oil can be fed into the contact area between the non-stick disk and the armature or the pole core.

Abstract: A connector apparatus connects the flat electrical conductors of a photovoltaic panel with a plurality of insulated electrical output conductors, respectively. The terminal portions of the flat conductors are bent into electrical engagement with corresponding blade contacts mounted on the photovoltaic panel. A plurality of resilient first electrical contacts are clamped in electrical engagement with the flat conductor bent portions, respectively, and a plurality of second electrical contacts are connected with the output conductors, respectively. An electrical circuit including a plurality of diodes is connected between the first and second electrical contacts. In order to dissipate the heat generated by the diodes, the diodes are mounted on a heat conducting plate that transmits the heat toward the photovoltaic panel. A cover member formed of heat conducting material is adhesively secured to the panel to enclose the connector arrangement, thereby to also transfer the diode-generated heat to the panel.

Abstract: A connector arrangement is provided for supplying electric power to a three-phase motor to produce motor operation in either a delta mode or a star mode, use being made of modular units that are removably mounted within a chamber contained in an outer frame that is secured to the motor housing. A power supply module arranged within the chamber includes a main receptacle containing a stack of terminal blocks having bus bars that transmit to the motor windings three-phase power that is supplied either by external power supply lines that extend into the chamber though openings contained in the side walls of the outer frame, or from an inverter arranged externally of the outer frame. Auxiliary receptacles are removably connected with the external surface of the main receptacle for monitoring the operating condition of the motor, or for controlling a motor operation, such as braking.

Abstract: A connector arrangement connects the flat conductors that extend upwardly from a horizontal photovoltaic cell panel with the insulated conductors of a cable via the circuits of a printed circuit board, respectively. A flat conductor support member is adhesively secured to the upper surface of the horizontal photovoltaic cell panel and includes upwardly extending bridge portions having flat upper edges about which are reversely bent the upper free ends of the flat conductors. A hollow sectional connector housing includes a lower body section containing a bottom opening that receives the flat conductor support member when the lower body section is seated on the panel upper surface. Bifurcated resilient contacts mounted on the lower section have first portions that engage the bent flat conductor ends, respectively, and second portions that engage the circuits on a replaceable printed circuit board carried by the removable upper cover section of the housing.
