The pressure spring K 71041 is a precision-engineered elastic component designed to work in conjunction with slide K 71037 within the oil pump mechanism of the Sulzer ZV40/48 engine. Its primary function is to apply a controlled force that ensures consistent contact and positioning of the slide during operation. Subjected to repeated compression cycles, vibration, and thermal influences, this spring is manufactured from high-grade spring steel to maintain its elasticity and performance over extended service life. By providing stable force distribution and compensating for minor variations in movement, the K 71041 pressure spring enhances the efficiency, responsiveness, and reliability of the oil pump system.
