As I understand it, since 2011, new elections can only be caused by specific wording issued in the House of Commons and then voted upon by a two-thirds majority. As it stands, May is immune to her own party's machinations until December (unless she is forced to resign by peer pressure) and the sitting Tory MPs will of course not support a vote of no-confidence in the government, because they might then lose their jobs (shock! horror!) in the forthcoming election.
Depending on how badly the three votes go this week, Parliament may even order the Prime Minister to seek an extension (or even repeal Article 50). I'm not sure how likely that is, but it's clear that May is not alone in the driving seat and may even have lost control of the steering wheel.
