Abstract
Official abstract text for this publication.
There is provided a ratchet-type tensioner whose spring stopping washer for seating a ratchet biasing spring is rigidly and readily assembled to a ratchet-receiving hole so as not to fall out of the ratchet-receiving hole and which reduces flapping noise and prevents seizure of the plunger by securely and stably operating a ratchet mechanism in operating an engine. The ratchet-type tensioner 100 is arranged so that the spring stopping washer has a C-ring anchored in the rear-end area of the ratchet-receiving hole by fitting in a diameter-reduced state and by enlarging its diameter within an anchoring circumferential groove of the ratchet-receiving hole and a spring stopping piece extended from the C-ring to a ring center area to seat the ratchet biasing spring.
First claim
Opening claim text (preview).
The invention claimed is: 1. A ratchet-type tensioner, comprising: a housing body in which an oil passage for supplying external pressure oil is formed; a plunger-accommodating hole formed in the housing body; a plunger projecting out of the plunger-accommodating hole toward a traveling chain, and slidable in said plunger-accommodating hole in an advance/setback direction; a high-pressure oil chamber formed between the plunger-accommodating hole of said housing body and a ho…
