Title: Water quantity adjusting valve device of marine propeller
Inventor: NISHIMURA SEIICHI
IPC: F02B61/04
Filed: 1982-07-23
Abstract: PURPOSE:To obtain a reliable closed condition of a valve and ensure a smooth operation of an internal-combustion engine by allowing a valve seat and a valve body to be brought into contact under a line contact condition. CONSTITUTION:The contact section between a valve seat 27 and valve body 31 when a temperature sensing valve 25 is closed is made a line contact and the contact area is made the minimum. Therefore, even if dirt such as sand grains infiltrates between the valve seat 27 and valve body 31 when they are separated, the dirt is discharged to either a water jacket 19 side or a water discharge path 24 side when they are brought into contact without being retained at the contact section, thus the leak occurrence of the temperature sensing valve 25 can be suppressed. In addition, the contact face pressure between the valve seat 27 and valve body 31 becomes high, thereby even if fiber-like dirt is bitten between the valve seat 27 and valve body 31, the dirt is cut off or compressed when the valve seat 27 and valve body 31 are brought into contact, thus suppressing the leak occurrence of the temperature sensing valve 25.
