Switchable rocker arm with lash adjustment and travel stop

A rocker arm for transmitting rotational motion from a camshaft to opening and closing motion of a combustion valve in an internal combustion engine, said rocker arm comprising:

• an outer arm;
• an inner arm having an inner follower configured to follow said camshaft, wherein said outer arm and said inner arm selectively pivot relative to each other;
• a lock pin which moves between 1) a coupled position in which said lock pin prevents said inner arm from pivoting relative to said outer arm past a predetermined position of said inner arm relative to said outer arm in a first direction and 2) a decoupled position in which said lock pin permits said inner arm to pivot relative to said outer arm past said predetermined position in said first direction;
• a lost motion spring which biases said inner arm to pivot relative to said outer arm in a second direction which is opposite of said first direction;
• and
• a travel stop extending along a travel stop axis and having a travel stop surface which surrounds said travel stop axis such that said travel stop surface is eccentric to said travel stop axis, said travel stop being supported by one of said inner arm and said outer arm such that a remaining one of said inner arm and said outer arm which is opposite of said one of said inner arm and said outer arm which supports said travel stop supports a complementary stop surface which engages said travel stop surface thereby limiting an extent to which said inner arm pivots relative to said outer arm in said second direction;
• wherein the extent to which said inner arm pivots relative to said outer arm in said second direction is dependent upon a rotational position of said travel stop about said travel stop axis.
