Abstract
A coolant buffering apparatus of a CRT that buffers expansions and contractions of a coolant held in a coupler installed between the CRT and a projection lens unit. The apparatus has a cylinder connected to the coupler so that coolant in the coupler can flow into the cylinder, a piston assembly installed to be operative to reciprocate in the cylinder and pushed in a direction away from the coupler as coolant expands, and a spring for elastically biasing the piston assembly toward the coupler when the coolant contracts.
Claims6
A coolant buffering apparatus of a cathode ray tube (CRT) for buffering expansions and contractions of a coolant held in a coupler installed between said CRT and a projection lens unit, said coolant buffering apparatus comprising:
- a cylinder with a first end and a second end, said first end connected to said coupler so that said coolant in said coupler can flow into said cylinder;
- a piston assembly installed to be operative to reciprocate in said cylinder to be pushed in a direction away from said coupler in said cylinder as said coolant expands;
- and
- a spring for elastically biasing said piston assembly toward said coupler as said coolant contracts.
