Abstract
This invention is about the lock mechanism which prevents the oil inside the cylinder to leak back because of wear, cut or blast that may occur on the hoses used in hydraulic and pneumatic piston systems its' characteristics is having; a body (1) in a cylindrical form, a second coupling (3) that enables the fluid inside the body (1) to enter-exit the casing inside the hydraulic cylinder (H) and move towards +x and -x in a way to make the cylinder shaft to move forward and backward, a lock-casing (5) located inside the body with the screw threads on it and including a semispherical housing at the end, a pin lock (8) located in the semispherical housing at the end of the lock-casing (5) and moves toward +y and -y inside this housing in a way to allow the fluid flowing through this casing to enter and exit, an unlocking pin (4) that enables the pin lock (8) to move toward +y and forms a semispherical shape at the end, a lock spring (7) located inside the lock-casing (5) in a way to enable the pin lock (8) to move toward -y with compression force, a pin spring (6) that enables the unlocking pin (4) to move toward -y with compression force, a first coupling (2) that enables the fluid to be transferred and sent back to the pressure gap (B) in a way to allow the unlocking pin (4) to move toward +y and an end cap (9) that prevents the oil to leak out from the pressure gap (B) at the back of the body (1).
