Windshield washer pump check valve
Has anyone ever messed with windshield washer pumps? Both the Pre A and later pumps have a check valve like the one shown. It appears to have a ball in it that must allow passage thru the valve one way only. I have some of the valves that are missing the ball. (they are not the ones that are designed with no valve). The barrel of the check valve has an internal thread, which indicates that there might be a threaded part that traps the ball. Can anyone shed light on this?

Just that the valve causes the rubber dome to suck fluid only from the reservoir as it pops back up, and it keeps the squirter lines from draining between uses.

I understand the check valve's function. What I am interested in is its construction, so that I can repair the valves I have that are missing parts.

Jim,
A long story with many people involved resulting in making a small run of pre A washer pumps and their related parts... On pre A pumps there are several different version of the valves... The springs and the check balls are readily available... in refurbishing an existing valves assembly be sure to check and or clean the ball seat... if you need help contact me...

a few more images... the first images shows the difference in valves... other related sundries and trivia...
I hate to try to list people because I am sure to leave someone off the list... some people who were key in this project were James Davis, David McPherson, Curt Dansby, Edwin Schweitzer and others...- James Davies

Re: Windshield washer pump check valve
Clearly Rick has!
Btw Rick, a new data point - the barrel shaped pump housings did come with the threaded plunger rod with the "W" knob in ~Aug 1953. So slightly different from the early 1953 ones with the aluminum knob and set screw, and different again from the early 1954 cylinder-shaped bodies with the "W" knob. Good fun. We will have to do some modifications to mine. Data from Jeroen.
