Title:
VALVE-SPINDLE SEALING DEVICE
Document Type and Number:
Japanese Patent JPS62118177
Kind Code:
A
Abstract:
An improved seal (44) for a reciprocating valve journalled in a valve guide is formed of a resilient elastomeric material and includes a valve stem sealing section (50) and a valve guide sealing section (52). A helical spring (48) is co-axially embedded in the seal. The spring (48) is preferably formed from a single piece of round wire extending throughout both of the sealing sections (50, 52). Alternatively, the spring can be formed in two pieces (62, 66, Figure 3), one for each of the sealing sections, or can be formed from flat wire (84, Figure 4). The seal can be quickly and easily installed about a reciprocable valve (28) in an internal combustion engine.
