Title:
HEAD FOR PNEUMATIC PUMP
Document Type and Number:
Japanese Patent JPS5783679
Kind Code:
A
Abstract:
A head of an air pump for inflating pneumatic tires having a motorcycle valve comprises a pot-shaped housing defining a pressure space. The housing is arranged to be connected to an air pump defining a piston space so that the pressure space and the piston space are in communication with one another. A projection is formed integral with the pot-shaped housing and defines a cavity appliable upon a motorcycle valve including a valve body and a spring-biased check valve. A partition is provided between the cavity and the pressure space, the cavity of the projection communicating by at least one air duct passing through the partition with the pressure space. A check valve is provided in the cavity of the projection and is defined by a seal arranged around a lifting pin projecting from the partition into the cavity and leaving free between itself and the lifting pin a connecting duct. This seal forms with its free end face a sealing surface facially engaging the motorcycle valve body upon lifting of the spring-biased check valve of the motorcycle valve body accommodated by the projection by the lifting pin and engages with a sealing lip at the connecting duct side the lifting pin in shutting off the air duct to the pressure space.
