Abstract
Official abstract text for this publication.
An electromagnetic switch for a starter. The electromagnetic switch includes a cylindrical slidable member that is separate from a plunger, loosely encompasses an outer circumferential periphery of a plunger rod, and is axially movable integrally with the plunger. The slidable member is at least partially axially inserted into an inner circumferential periphery of a cylindrical bore. The slidable member has a sliding surface such that, when the solenoid is in its inactive state, the sliding surface is entirely circumferentially in sliding contact with the inner circumferential periphery of the cylindrical bore, and has a vent groove axially extending on the outer circumferential periphery of the slidable member such that, when the solenoid is in its active state, a plunger compartment and the contact compartment are in fluid communication with each other via the vent groove.
First claim
Opening claim text (preview).
What is claimed is: 1. An electromagnetic switch for a starter, comprising: a main contact provided on a motor circuit for the starter and configured to interrupt energization current to a motor; and a solenoid configured to open and close the main contact in response to ON/OFF operation of an electromagnet, the solenoid comprising a coil configured to form the electromagnet through energization, a plunger movable axially on an inner circumferential periphery of the coil,…
