摘要:
A heat exchanging system suitable for use in an exhaust gas recirculation (EGR) circuit comprises a split EGR heat exchanger arrangement. Exhaust gas is used to warm engine oil via a first heat exchanger during initial stages of an engine operating cycle. In the later stages of the operating cycle, recirculated exhaust gases are diverted to flow through the second heat exchanger where they are cooled by the engine coolant.

A lamp with a built-in lamp which is inserted into a base via a mounting clip and is surrounded by an enveloping bulb. The base and the enveloping bulb are joined via a joining compound or using a clamping technique. The mounting clip has securing elements, via which the enveloping bulb is held on the base once the joint has loosened.

The subject matter of the disclosure is a PAR lamp arrangement having an integral lamp, in particular an integral halogen lamp, which is inserted into a base and is surrounded at least in sections by a reflector, the base and the integral lamp being connected via contact springs, and the reflector being covered by a diffusing screen. According to the invention, the reflector is made from aluminum and is provided with a reflective surface or coating. Owing to the aluminum reflector used and the fact that the integral lamp is held via contact springs, improved holding of the integral lamp is made possible with reduced weight and production complexity.
摘要:
The invention relates to a lamp (1), particularly a mains-operated halogen lamp, comprising a luminous element (8) that is fixed at least at one mounting point by means of exactly one funnel-shaped recess, i.e. a knob (10a-10d), which is formed from the lamp vessel (2). Each knob (10a-10d) extends substantially perpendicular to the longitudinal axis (L) of the lamp (1).

The invention herein relates to pumps and valving arrangements for fluid dispensers. The invention further relates to dispensers incorporating a pump. The pumps herein comprise a dose chamber, a resilient actuator, valves for controlling the flow of fluid into and out of the dose chamber and the upper and lower pump halves each formed from unitary mouldings, at least the upper pump half comprising a semirigid, thermoplastic material. The pumps are easily made via injection moulding from a small number of parts. Combination of the pump with a fluid reservoir provides a fluid dispenser which may further comprise an atomiser for forming a spray as fluid is ejected from a dispenser outlet. Methods of making the pump and valving arrangements are also provided by the invention.
摘要:
An electric lamp is provided with a base at one end, having an outer bulb supported in a base, and at least one integral lamp, held inside the outer bulb by means of a mounting clip, the mounting clip being fixed on a stem, and the stem having a lower region and an upper region, and the cross-sectional area of the upper region being smaller than the cross-sectional area of the lower region, wherein the mounting clip is fixed on the upper region of the stem.
摘要:
The present invention relates to an electrical incandescent lamp (1), in particular a halogen incandescent lamp, in which luminous element limbs (14, 16) extend in lamp vessel structural parts (42, 44), the lamp vessel structural parts surrounding the luminous element limbs in sections at a distance, and the axes of the lamp vessel structural parts (42, 44) extending at a distance from one another in order to increase the energy efficiency of the incandescent lamp, in particular if a layer (42a, 44a) which reflects IR radiation is applied to the lamp vessel structural parts. When using the pinch-sealing technology, it is possible to achieve a small system voltage halogen lamp having a long life expectancy and at the same time requiring little energy for reaching the operating temperature.
摘要:
The invention relates to an electric lamp (1) with a base at one end and with an outer bulb (3), mounted in a base (2), and at least one integral lamp (4), preferably a high-voltage halogen lamp, which is arranged within the outer bulb (3), and at least two power supply wires (6) from the base (2) to the integral lamp (4), the integral lamp (4) being held on the power supply wires (6). At least one of the power supply wires (6) has, in the region of the end (12) on the integral-lamp side, at least one u-shaped bend (11) for accommodating a base (8) of the integral lamp (4).
