Oil spray nozzles are primarily used for piston cooling in high-performance combustion engines. They prevent thermal damage to the engine, reduce the combustion chamber temperature and thus enable maximum performance.
Oil spray nozzles, also known as piston cooling nozzles, can be used in all combustion engines. Our nozzles are currently used in motorcycles, cars and even trains.
However, oil spray nozzles are also used for chain lubrication, clutch or generator cooling.
Our oil spray nozzles are specially adapted to the respective customer requirements.
Our products are developed, tested and manufactured in Germany. This enables us to guarantee the highest quality and safety.
Oil spray nozzles are installed underneath the piston in the engine block and spray the piston crown with the required amount of oil with pinpoint accuracy. Some pistons have an internal cooling channel that guides the oil through the piston. This makes it possible to direct the cooling medium particularly close to the highly stressed areas.
Depending on the customer’s installation space, there are two basic variants to choose from:
Variant 1
Here, the outlet pipe is firmly connected to the nozzle body, which contains a ball-spring or piston-spring system, and to a retaining plate. The oil spray nozzle can be mounted on the customer’s premises using the retaining plate.
Variant 2
In this variant, a ball-spring system is located in a banjo bolt. The word “banjo bolt” describes a screw with a cavity and transverse holes that makes the cavity accessible from the outside. The bolt is connected to a carrier and the tube attached to the carrier. Fastening in the engine block takes place directly via the banjo bolt.
The tubes are usually provided with a retraction. This is a tapering of the outlet cross-section. It increases the jet quality and accuracy and is used to regulate the oil flow rate.
Some of our variants are equipped with two pipes. These can either be used to cool two pistons at the same time or for one tube to direct the oil into the piston cooling channel and the other tube to the piston crown.
Parameters such as opening and closing pressure are defined by selecting the compression spring and its installation position in the system.
With these components, the right oil spray nozzle can be generated for every application.
